Anti-backlash gear can improve the static transmission precision of system. Besides, the dynamic characteristics of anti-backlash gear system have a significant effect on the performance of overall mechanism, and the torsion spring preload of anti-backlash gear is an important factor to affect the dynamic characteristic. In order to study dynamic characteristics of the anti-backlash gear, a rigid-flexible coupling model of single-stage anti-backlash system was established based on ADAMS / Flex, and the simulation accuracy was compared with the pure rigid model. The effect of the torsion spring preload on frequency response of the anti-backlash system was studied by virtual sweep experiments.

Engineering Significance

This thesis studies how reinforced steel completes digital length design after being straightened.In general,the analysis of kinematic and dynamic to reinforced steel does not be considered the role of the flexible components in institutional kinematic. The program regards reinforced steel as a flexible body and sees friction wheel as rigid body. The contact between friction wheel and steel is the rigid-flexible coupling[3].With the simulation analysis in ADAMS,I research the problem that reinforced steel produces the slide or not in different speed and contact friction coefficient, in order to determine the design and operating parameters of the cut-to-length body and ensure the accuracy. The result has a good engineering significance in the design of the length structure optimization and operating parameters [4].

The Dynamics Analysis & Simulation of the Rocket Sled were done based on Multibody System Dynamics and Finite Element Analysis Theory. The most difficult work in the analysis was establishing the boundary conditions of the rocket sled. The paper made this kind of attempt. Then the relevant post processing figures and data were obtained, thereby providing the designer and manufacturer with detailed and reliable data. The conclusion is the simulation method is more effective than those before and the boundary conditions is correct and acceptable.
