Design of Space Sliding Rails and Mechanical Analysis
Unlike commercial sliding rails, space sliding rails need to meet complex mechanical requirements in the state of ground tooling, launch and on-orbit. The former could slide smoothly while their carrying capacity is low. As a result, they cannot be applied directly to the space stations, manned spacecrafts and other space probes. Hence, it is necessary to design a kind of full-pulling sliding rails which can be suitable for three completely different mechanical conditions. In this paper, we firstly built the mechanical models of the ground tooling, launch and on-orbit state, then a kind of sliding rails is designed according to the mechanical models, finally, a simulation analysis was carried out on the designed sliding rail. The result shows that this kind of sliding rails meets all the design requirements, which verifies the validity of the models.
