| 中文摘要: |
| 冲击响应谱（SRS）试验已经成为大多数航天产品必做的力学环境试验项目之一， 而利用电动振动台进行模拟试验已成为常用方法。在试验实施过程中如果控制策略、 参数设置不合理， 经常导致控制过试验/欠试验， 或者持续时间过长等问题。文中利用小波合成冲击响应谱原理， 结合SD2560控制系统， 通过调试和试验确定如何较好地利用振动台开展冲击响应谱试验， 给出了小波各参数的确定及优化方法。 |

| SRS test has become one of the required dynamics tests of most spacecraft products. Simulation test with electric shaker has become a common method. The problems of over test, under test, and too long duration often exist due to improper application of control strategy and parameter setting. The methods of parameter determination and optimization using the theory of wavelets synthesis for SRS were put forward. The ways to carry correct SRS test by shaker as well as the SD2560 control system were discussed through examinations and tests. |
