| 摘 要： | 介绍了固体火箭发动机静止试验动态推力的测量方法。首先对试验台架和发动机进行动态校准得到系统的响应函数，然后利用频率响应函数对试验过程中测到的输出力函数进行恢复，以获得真实的输入力函数。实践证明，频域恢复技术是有效的途径之一。

| Abstract: | measurement method of dynamic thrust for solid rocket motors in static testing is introduced.First, the test fixture and solid rocket motor system is calibrated to obtain the frequency response function.Then by using the frequency response functon, the output thrust function measured during the test is returned to normal' So as to obtain the true input thrust function. Practice has proved that the skill of returning frequency domain to normal is one of effective methods. |
