Research on Simulation and Verification PlatformTechnology forSpacecraft Transport Container

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