摘要：
Aiming at the design of space lenticular boom deployable mechanism, an explicit dynamic algorithm combined with high-performance computing resource is adopted to perform non-linear quasi-static simulation of stowing and deploying process. To meet the large-scale calculating demand due to simulation debugging and multiple loadcases, the explicit calculation parallel speed-up strategy is appropriately established by increasing loading rate after comparison and analysis of time cost, stress and energy curves. The results shows that dynamic simulation method can be used to predict the function design, structure reform, and parameter adjustment as well as provide guidance and reference for experiments.
