| 摘 要： | 在连续小波变换的基础上，对线性时不变振动系统进行了小波分析，给出了系统输出信号的小波变换的脉冲响应和输入的关系，作为应用实例，计算了单自由度系统的输出信号的小波变换，并与输出信号的直接小波变换进行了比较，结果表明两者完全吻合。

| Abstract: | The linear time invariant vibration system is analyzed by Continuous Wavelet Transform(CWT),the relationship of wavelet transform of output signal with the pulse response of system and input signal is put forward.As an exapmle,the wavelet transform of the output signal of system with single degree of freedom is calculated and compared with the direct wavelet transform result of the actual output signal,it shows that the two results are in complete agreement. |
