| 目的 探寻利用振动信号分析仪采集冲击试验数据的方法， 并验证新方法数据的可信度。方法首先， 从力学模型、 数据采集理论及信号处理原理等3方面入手， 分析振动试验与冲击试验数据采集的异同点， 为新方法提供思路及理论支持。其次， 以OROS动态信号分析仪为具体研究对象， 以常规冲击试验数据采集仪Shock Manager为对比仪器进行验证性冲击试验， 进而提出基于OROS动态信号分析仪的冲击试验数据采集方法及具体参数设定。最后， 对比实验结果并进行误差分析以验证新方法的可信度。结果 利用OROS动态信号分析仪采集的冲击波形与常规冲击试验数据采集仪所得数据比较可知， 表征冲击响应波形的三大要素 （最大加速度、 作用时间及速度变化） 的吻合度均很高。结论 将通常用于振动试验的动态信号分析仪进行冲击试验数据采集的思路是切实可行的。 |

| Objective To seek a data acquisition method of the shock test using a vibration signal analyzer, and to verify the feasibility of the new method. Methods First, the similarities and differences between the data acquisition of the shock and vibration tests were compared by considering mechanical model, data acquisition theory and signal process, which provided ideas and theoretical support for the new method. Second, using OROS dynamic signal analyzer and conventional data collection instrument—Shock manager, a confirmatory shock test was carried out, furthermore, a new data collection method of shock test using vibration signal analyzer was proposed and the parameter setup conditions were confirmed. Finally, using the experimental results, error analysis was conducted to verify the feasibility and reliability of the new method. Results By comparing the experimental results measured through OROS dynamic signal analyzer and Shock manager, the three factors of the response pulses of the shock test were highly matched. Conclusion It was proved that the vibration signal analyzer could be used to acquire the experimental data of the shock test. |
