摘　　要：为改善返回舱座椅缓冲系统的性能,提出一种新的改进方案,将其脚部由铰接支撑改为斜置弹性支撑。在ADAMS中建立座椅缓冲系统的动力学模型,并采用参数化建模方法对斜置弹性支撑的参数进行优化设计。对优化后的座椅缓冲系统进行动力学仿真的结果表明,与改进前座椅系统的缓冲性能相比,优化后的座椅缓冲系统不仅没有增加胸背向冲击响应,而且显著改善了人体头盆向的冲击响应。A new plan was presented to improve the performance of seat-buffer system of reentry capsule.The articulated sustentation was changed into sideling elastic sustentation.The dynamics model of seat-buffer system was established by using ADAMS.With the method of parameterized modeling,optimal design for the parameters of sideling elastic sustentation was accomplished.The dynamic simulation results show that the optimized seat-buffer system not only decreases the shock response in chest-back direction,but also ...
