| 摘 要： | 通过相同激励条件下对三种典型振动试验夹具进行宽频段随机振动试验分析,发现夹具在试验频段内出现不同程度的共振现象,过试验现象严重。通过三种典型振动试验夹具质量、一阶固有频率、位移变化量及应变变化量等数据对比、分析,得出影响振动试验夹具振动传递特性的主要因素,以影响因素为优化变量,以典型部位平均响应与输入的振动传递比为优化目标,进行拓扑优化设计,最终经过夹具振动试验验证,过试验情况得到有效控制,满足相关规范要求,为固体火箭发动机振动试验控制提供保障。

| Abstract: | Through the same incentive conditions of three typical solid rocket motor vibration test fixture for vibration test analysis, different degree resonance phenomena within the test frequency and the experiment phenomenon were found. Through test data analysis, it was concluded that the main factors influencing the vibration test fixture transfer characteristics, influencing factors as optimization variables, the average values of vibration response and the input value in a typical part error as the optimization goal, fixture topology optimization design, the final test optimization model experiment phenomenon under control, meet the specification requirements, provide guarantee for solid rocket motor vibration test control. |
