| 摘 要： | 通过用复模态分析得来的频率响应函数矩阵,分析了可变阻尼参数对频响函数的灵敏度,从而得出响应功率谱及其响应加速度对阻尼参数的变化率,并将此理论应用到汽车减振阻尼参数优化控制中。

| Abstract: | A simplified procedure is presented for the determintion of rates of change of frequency response function matrix of system for the non-proportional changeable damping ,by means of the second order perturbation technique in conjunction with complex modal analysis. Consequently, when excitation information in frequency domain is known,the sensitivity of the response power spectra and the response time history can be obtained. |

| Keywords: | non-proportional damping frequency-response function second order perturba-tion shock absorption |
