Abstract: To meet at the requirements of vibration reduction and heat preservation analysis subject to a limited number of physical tests, a dynamic and thermal simulation method for spacecraft transport container is proposed.Firstly rigid flexible coupled multi body dynamics system is established for spacecraft transport container, and a virtual performance test for vibration reduction is implemented by input excitation, which is generated from the physical railway lines test. Then a thermal model of the spacecraft transport container is established based on computational fluid dynamics, and a virtual performance test for heat preservation is implemented by simulation of natural convection and air condition. Finally, a simulation and verification platform is established based on C/S frameworks and a series of navigation interfaces, and simulation results of the platform are proved highly consistent with the physical test.
