说明：  用于高校学生 转子振动台轴跳动轨迹分析仿真实验。采用正交的具有相位差的两列正弦波来模拟传感器测到的X方向和Y方向的轴跳动。包括信号的时频分析，滤波处理，叠加还原和边界检验。参数可自定
(For college students beat the rotor shaft vibration table trajectory analysis simulation. With orthogonal phase difference of two sine waves to simulate the sensor measured the X-axis direction and Y direction of beating. Including time-frequency analysis, filtering, reduction and border overlay test. Parameters can be customized)
