空间豆荚杆机构收展过程的并行仿真计算

针对空间豆荚杆展开机构的设计，利用显式动态算法和高性能计算资源，对豆荚杆盘卷收拢和展开过程进行了非线性准静态仿真。为满足计算调试和多组工况带来的大规模计算需求，通过计算耗时、应力曲线和能量曲线的对比分析，确立了以提高加载速率为主的显式计算并行加速合理策略。计算过程和结果分析表明，动态仿真方法完全可以用来对豆荚杆机构的功能设计、结构改型和参数调整进行预知仿真，并为试验提供指导和参考。

Parallel Computing for Simulation of Stowing and Deployment Process of Space Lenticular Boom Mechanism

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 r...
