Research on Torque Loading Technology Based on L Lever in Spacecraft Bolt
Beijing Institute of Spacecraft Environment Engineering, Beijing, China
As the main form of structure assembly, the stability of bolt joint is directly related to the performance of spacecraft. This essay is used to analyze the cause of standard torque spanner which is not suitable to the tightening torque and summarized according to different operating conditions. Based on thorough analysis of fastening principles and principle of type serialization, a scheme of integrated L Lever is established. The results of experimentation indicate that the scheme of integrated L Lever is reasonable along with the requirement of developing long-life and high-reliability spacecraft. Therefore, the stability of fasteners is greatly enhanced.
Key words: L Lever / spacecraft / bolt / torque
