用matlab仿真轴承故障信号构造轴承故障的仿真信号，其中轴承的固有频率fn=3000Hz , 位移常数y0=5, 阻尼系数ξ＝0.1, 冲击故障发生的周期为0.01s，采样频率fs=20KHz, 采样点数N=4096。要求：根据上述条件构造轴承故障的仿真信号，画出其时域波形及频谱图。-Matlab simulation bearing fault signal

轴承故障仿真信号时域波形图和轴承故障仿真信号幅度谱图的MATLAB程序(Bearing fault simulation signal time domain waveform and amplitude spectrum)

包含三个M文件，程序为本人自行编译完成，Demo中设有仿真信号验证，并经本人实际齿轮箱信号（轴承外圈故障）测试，经包络分析结果显示能够有效定位轴承外圈故障频率。 亲测可用。(It contains three M files. The program is compiled and completed by myself. Demo has simulation signal validation. It has been tested by my actual gear box signal

更改参数可以获得不同大小缺陷的仿真信号，并且画出相应的图像，可以用于轴承故障定量诊断(The simulation signals of different size defects can be obtained by changing the parameters.)
