| 目的 提高振动台冲击响应谱试验模拟能力。方法 分析影响振动台冲击响应谱模拟能力的原因， 提出通过改变连接特性提高振动台冲击响应谱模拟能力的方法， 并对该方法进行理论分析和试验验证。结果 利用具有谐振效应的台面能够将160 kN振动台冲击响应谱量级由原来的1000g提高至2000g， 并能够实现负载情况下1600g的冲击响应谱试验， 提高了振动台冲击响应谱模拟能力。结论 通过改变连接特性可以提高振动台冲击响应谱模拟能力， 同时应尽量避免使用振动试验夹具进行冲击试验， 针对产品试验要求设计冲击试验夹具， 能够获得更理想的冲击试验效果。 |

| Objective To improve the shock response level of shaker. Methods The reasons that influenced the shock response level of shaker were analyzed. Then the method to improve the shock response level of shaker by changing linking characteristic was put forward, while the theoretical analysis and the test demonstration were carried out. Results The SRS level with 160 kN shaker could be improved from 1000g to 2000g by using the table with harmonic response. The SRS level under load of 1600g could be conducted. The shock response was improved. Conclusion The shock response level of shaker can be improved by changing linking characteristic, at the same time, the fixture of vibration should be avoided. The effect of SRS can be better with the fixture of vibration which are designed as required. |
