Reuniting with First Love

The following is a summary and reflection on the bolt connection experiment: ###1. Summing Up 1. ** Achievement of experiment objective ** - The relationship curve between the force and the distortion of the bolt connection under the working load was successfully tested (distortion coordination diagram). This result helped to understand the internal relationship between the force and the displacement of the bolt when it was subjected to an axial-working load, and provided a theoretical basis for the design and optimization of bolt connections in practical engineering applications. - The stiffness of the bolt C1, the stiffness of the connected part C2 and the relative stiffness C1C2 were calculated accurately. The determination of these parameters is crucial to evaluate the overall performance of the bolted connection. They directly affect the reliability and stability of the bolted connection under different working conditions. - The influence of the pre-tightening force and the relative stiffness on the stress amplitude was clarified, and then the influence on the bolt fatigue was investigated. It provided valuable data support for preventing bolt fatigue failure, and was helpful to determine the reasonable pre-tightening force in engineering design and prolong the service life of the bolt. 2. ** Function of experimental equipment and instruments ** - The structure of the experimental machine was reasonable. For example, the LB-type bolt connection experimental machine, the handwheel, the sleeve, the force measuring ring and other components cooperated with each other. The handwheel was used for pretightening, the sleeve was used to simulate the connected parts, and the force measuring ring was used to measure the working load. Through the cooperation of these components, the test of the bolt connection under different stress conditions was realized. - Resistance strain gages and resistance strain gages played a key role. The resistance strain gauge attached to the bolt rod and sleeve could sense the strain, and then the strain was measured by the resistance strain gauge to calculate the force and distortion. This measurement method had high accuracy, which provided a guarantee for accurate experimental data. - The stiffness of the force-measuring ring, the reading of the dial indicator, and other parameters were directly proportional to the load, making the measurement of the load more intuitive and accurate. 3. ** Understanding and application of experimental principles ** - Based on the principle that the pre-tightening force of the bolt and the connected part was equal, the force and the distortion diagram of the two parts were drawn in the same coordinate system to obtain the distortion coordination diagram. This principle clearly showed the process of bolt extension and compression of the connected parts, as well as the relationship between the bolt tension and the compression force of the connected parts under the action of the axial-working load. - The concept of stiffness, namely the ratio of force to displacement, was clarified. The stiffness of bolt C1, the stiffness of the connected parts C2 and the relative stiffness C1 and C2 were reflected in the force-displacement diagram as the slope of the graph. It was helpful to understand the mechanical properties of bolted connection system and provide theoretical guidance for the optimization of bolted connection structure. ###2. Reflection 1. ** Analysis of sources of experimental errors ** - The precision of the instrument might bring errors. Although instruments such as resistance strain gages and strain gages could provide more accurate measurements, the sensitivity coefficient and accuracy level of the instrument itself may have a certain impact on the measurement results. For example, there might be some deviation in the reading of the strain gauge, which would affect the calculation of the force and distortion of the bolt and the connected parts. - The human factors in the experimental operation process could not be ignored. In the process of tightening the handwheel for pre-tightening and loading, it was difficult to ensure that the force and rotation angle of each operation were exactly the same, which might cause fluctuations in the pre-tightening force, which would affect the accuracy of the experimental results. In addition, when the resistance strain gauge was installed, if the position of the attachment was inaccurate or there was a problem with the attachment process, it would also affect the accurate sensing of the strain of the bolt and the connected parts. - The uneven distribution of experimental materials could also be one of the sources of error. Although the material of the bolt and the sleeve was specified to be No. 45 steel, there may be microstructural inequity in the actual material, such as grain size, impurity distribution, etc. This will lead to a certain degree of dispersion in the material's elastic module and other performance parameters, which will affect the repetitiveness and accuracy of the experimental results. 2. ** Discussion on the improvement measures of the experiment ** - Increase the precision of the instrument. They could choose higher-precision resistance strain gages and strain gages, and perform regular calibrations and maintenance on the instruments to ensure the accuracy of the instruments during the experiment. At the same time, for measuring components such as the force measuring ring, the precision could also be upgraded or the measurement method could be optimized to reduce the measurement error. - It was to regulate the experimental operation process. A detailed experimental operation manual was developed to clarify the operating specifications for pre-tightening and loading, such as the tightening speed of the handwheel, the number of rotations, and other operating parameters. The operator was also strictly trained to ensure the consistent operation. When the resistance strain gauge was installed, a standardized sticking process was used, and strict quality inspection was carried out to ensure the sticking quality of the strain gauge. - The selection and processing of experimental materials were optimized. In the selection of experimental materials, one could try to choose materials with more uniform quality and more stable performance. If conditions permitted, the material could be pre-treated, such as tempering, to improve the material's microscopic structure and reduce the dispersion of the material's properties. At the same time, the materials were strictly tested before the experiment, and the materials that met the requirements were selected for the experiment. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Quan Hongchan and Guo Jingjing both had outstanding performances in the field of diving, but they were in different periods, and their strengths were reflected in different aspects. Quan Hongchan became famous at a young age and showed amazing talent in the women's 10m platform event. In the 2021 Tokyo Olympic Games women's single 10m platform final, she scored full marks in five movements and three jumps, winning the gold medal with the highest score in the event's history. She had also achieved outstanding results in major events such as the World Swimming Championships, Diving World Cup, Asian Games, etc., such as winning the women's synchronized 10m platform and mixed all-around championship in 2022, and winning many times from 2023 to 2024. Guo Jingjing was a legendary figure in the diving world. She was well-rounded and experienced in platform and springboard events. She once dominated the diving world in her career. She had won numerous awards in many international competitions, and with her deep professionalism, she could serve as a diving technical officer of the International Swimming Federation after retirement and return to the diving world as a referee. Therefore, it was difficult to determine who was better, Quan Hongchan or Guo Jingjing. Both of them had written colorful chapters in the history of diving. While watching the Olympics, you can also read the wonderful novels related to the Olympics!

If she had transmigrated into Tang San's daughter, Tang Wutong, she would have faced many unique circumstances in the Douluo Continent world. From the perspective of bloodline, Tang Wutong possessed the formidable Tang Clan bloodline, which included the inheritance spirit Clear Sky Hammer. This bloodline was rather powerful on the Douluo Continent. After all, the Clear Sky School relied on the Clear Sky Hammer to become the continent's number one sect. At the same time, she also possessed the Blue Silver Emperor bloodline. Even though she hadn't awakened the Blue Silver Grass spirit, and the Blue Silver Emperor bloodline didn't show any obvious signs, this bloodline originated from Tang San, and its power wasn't inferior to the Tang clan bloodline. In addition, she also possessed the Soft Bone Rabbit bloodline from her mother Xiao Wu. In terms of identity, she came from the Douluo Divine Realm. She was the daughter of the Great Divine Circle's Supreme Divine King, the Sea God Asura God Tang San, and the Asura Sword Casket Xiao Wu. She was also the granddaughter of the Douluo Continent's plane lord Tang Hao and the life core Ah Yin. During her travels on the Douluo Continent, she disguised herself as a man and changed her name to "Wang Dong, Wang Dong 'er". She was a teacher in Shrek Academy's inner court and was one of the second generation of Shrek Seven Monsters. She was ranked seventh in age and became a second-level god of the Great Divine Circle after ascending to the Divine Realm-the Butterfly God. If she were to transmigrate, she would first possess a powerful foundation. She would be unrivaled on the Douluo Continent by virtue of her top-notch bloodline. Moreover, she would be able to achieve a martial soul fusion skill with Huo Yuhao. For example, she would be able to perform six great martial soul fusion skills. However, there were also some challenges, such as the risk of exposing her identity when she disguised as a man, as well as how to deal with the various interpersonal relationships brought about by her special identity in the process of getting along with others.

Aiya, this Little Song Jiafu was really a little unpredictable. Her acting skills were not bad. She had performed extremely well in many dramas. Perhaps it was because she lacked a representative work that was especially popular. It was the kind of super popular drama that would immediately remind people of her. Or perhaps he didn't do enough to promote himself. The competition in the entertainment industry was so intense now. Even if one had the ability, it would be difficult to become famous without enough exposure and topics. However, she also had her own group of loyal fans. It was just that her popularity was not as high as those S-list celebrities. While waiting for the TV series, he could also read the exciting content related to this site!

I recommend Immortal Qin, a historical fiction novel written by a man who dreams for ten years. It was about the protagonist waking up when the emperor of Zhou fell. He was in an era of chaotic warfare between the vassals, and there was a mysterious force behind him who wanted to dominate the nine provinces. The male protagonist, Zhao Zheng (Ying Zheng), wanted to shatter the darkness of the Nine Regions. There was also detailed information about the supporting male characters such as Zhao Xian and Ji Kong, such as their ages, birthdays, and astrological signs. Supreme Martial Arts was not bad either. It was a fantasy novel written by Chili Bibimbap. In this era where cultivation had reached a bottleneck, the ancient heritage had reappeared. A young man with a martial soul walked out of a small city, and a bloody storm began. He wrote more than 20,000 words a day, and it was super cool. "My Son Yang Jian Has the Postures of an Emperor" was very interesting. It was a work of Durian Wine. Yang Ling, the protagonist, transmigrated to Great Shang and wanted to enjoy life, but he became the father of Erlang God. He relied on doing a good deed every day to get rewards, and he was not afraid of facing the gods and demons in the end. There were also many interesting characters. The Big Guy from China Entertainment is also worth watching. I love Patretti. Gao Yang was reborn in 2004 and used the information gap to change the Chinese Entertainment industry from an actor to a director. Many characters had different personalities and characteristics. He Yuzhu's Large Model System of the Siheyuan, an urban novel written by Inevitable Loneliness.
