基于响应面法的缓冲结构参数优化设计
Optimization design for bumper structure parameters using response surface method
合理设计缓冲结构能够有效降低碰撞过程中的冲击载荷。使用LS-DYNA软件建立了返回舱着陆冲击的有限元模型，并通过试验结果对模型的有效性进行了验证。利用响应曲面优化方法，对返回舱底部和主梁之间缓冲结构的参数进行了优化设计。结果表明：优化设计后，主梁垂直方向加速度峰值比原始结构方案减小了38.5％，水平方向加速度峰值减小27.0％。响应面法是进行碰撞结构参数优化的有效方法。
Bumper structure can decrease impact loads effectively. The finite element model(FE) of re-entry module was developed by the software of LS-DYNA. The FE model was validated by comparing results of simulation and test. The parameters of bumper structure between main beam and bottom structure of re-entry module were optimized with response surface method. The results indicate that the acceleration peak value on the main structure in vertical direction decreased 38.5% compared to original structure and the acceleration peak value in horizontal direction decreased 27.0%. The response surface method is very effective for structure optimization design during impact.
