摘要	Screw joint structure is a basic device mostly used in space optical remote sensor assembly because of its outstanding advantages. Choosing the fitting fasteners and controlling the preload is the key to ensure the reliability of the screw joint structure. Plastering the locking adhesive on the screw thread during the course of assembling is a mean mostly used to prevent the screw joint get loose nowadays. But in the course of engineering application, the preload will change dramatically after plastering the locking adhesive on the screw threads or plastering different locking adhesive, although under the same locking torque. The quantified influence of the frequently-used locking adhesive in optical remote sensor assembling was analysed. The experiment results indicate that plastering the silastic(D04(L)) on the screw thread in the assembling, the preload will decrease by 50%~70% by comparison with the case of no locking adhesive under the same torque. But plastering the anaerobic adhesive(LOTTIE243), the preload will increase by 46%~98%. According to the study results, the influence to the preload has to be tested before using this kind of locking adhesive, and the torque should be adjusted according to the test results. The fastening by the torque spanner is unfit for the connection where the preload should be accurately controlled. 2015, Chinese Vibration Engineering Society. All right reserved.
