| 摘 要： | 本文用MSC／NASTRAN软件对再入飞行器复杂结构轴向随机振动试验和横向随机振动试验进行了响应分析，并与试验测量结果进行了比较，两者基本相符：加速度响应均方根值预示误差小于30％（轴向随机振动响应分析）和50％（横向随机振动响应分析）。本文采用的飞行器复杂结构随机振动响应分析方法和技术途径得到试验验证。

| Abstract: | The response analysis on axial and transverse random vibration tests of reentry vehicle complex structure have been done using software MSC/NASTRAN in this paper,and are compared with test results.Results of response analysis are closed to test results:the prediction erros of acceleration response RMS values are less than 30%(axial random vibration)and 50%(transverse random vibration).The method and technical route on random vibration response analysis of vehicle complex structure have been validated. |
