| 摘 要： | 将小波分析引入单自由度动力分析计算中。利用小波在时频域分析的特点，对动力荷载进行小波分解，滤去动力荷载的高频成分，以减少动力分析过程中的数据计算量，算例计算结果表明，按照动力体系特性利用小波分析去除动力荷载高频及其代表的荷载，误差在可接受的范围之内，不会影响动力体系的动力反应。

| Abstract: | The wavelet analysis is adopted in degree of single freedom dynamic system. Using the wavelet analysis, the high frequency of dynamic loads is discarded according to the wavelet feature that can analyzes in time frequency domain, and the data of loads in dynamic analysis progress is decreased. The calculated results for engineer show that the error deduced from the degree of single freedom dynamic system is in the accepted range. To use wavelet analysis to discard the high frequency and loads which are stand for in dynamic loads according to the properties of dynamic system is accepted and the method wouldn't affect the dynamic response greatly. |

| Keywords: | wavelet analysis dynamic response time frequency analysis |
