摘　　要：针对运载火箭运载能力提升引起的动载荷条件严苛化对结构动力学性能的高要求,以现役载人运载火箭整流罩飞船支撑结构为原型,对载人火箭整流罩和飞船之间的连接支撑结构进行了动响应拓扑优化设计。动响应分析采用模态加速度法,以在保证计算效率的前提下提高计算精度。动载荷分析结果表明,优化效果明显。The requirements on the dynamic performance of the structure become much higher due to the harsh load conditions induced by the substantial increase of the carrying capacity of the launch vehicle. The support structure between the spaceship and the fairing in the active manned rocket was taken as the prototype and the dynamic response topology optimization design was conducted for the supports between the spaceship and the fairing. Mode acceleration method （ MAM） was adopted to the dynamic response analysis method so as to improve the accuracy while without any compromise to the high efficiency. The dynamic load analysis showed that the effect of the optimization was promi-nent.
