摘要：In order to overcome the shortcomings of the physical test conditions, research and development of the spacecraft container simulation verification platform to enhance the level of digital development of the spacecraft container. Based on the theory of rigid-flexible coupling dynamics, the dynamic model of the box system is established. The dynamic external excitation is determined by obtaining the track spectrum and identifying the condition of the line. Based on the computational fluid dynamics, the thermal model of the spacecraft container is established, and the container is realized by simulating the natural convection and air conditioning control spacecraft container thermal simulation. Using modular design, C/S architecture and navigation process to achieve the simulation platform architecture versatility, ease of maintenance and scalability and other needs. Finally, the mechanics and thermal performance verification of the spacecraft container and physical test are carried out. The results show that the simulation results of the box dynamic system and the thermal system are in good agreement with the experimental results.
