摘　　要：对于位移、速度、加速度的分别校准目前已经达到了一定的水平,但对于同时校准位移、速度、加速度难度较大,基于傅里叶级数的基本原理,即凡是满足狄利克雷条件的信号均可用若干个正弦分量叠加产生,设计了一套运动装置.该装置可以产生两个正弦分量,并通过正弦分量的叠加产生出一个信号.伺服电机采用超前反馈实现系统的运动控制,结合伺服电机变频调速,实现运动速度的平稳提升.测试结果表明:该装置同时产生0～460mm位移,0～12m/s速度和0～5 000m/s2加速度,速度、加速度的测量误差小于1%.该校准装置可以用于运动测试设备的校准.Currently the respective calibration for displacement,velocity,acceleration has reached a certain level,while the simultaneous calibration for them is still very difficult.Based on Fourier series principle,that is,for any signal it can be generated by several superimposed sinusoidal components,as long as it satisfies the Dirichlet,a set of apparatus was designed,which could generate two sinusoidal components,then produce a signal by superimposing these sinusoidal components.Advanced feedback control was utilized in servo motor to realize the motion control of the system,combined with frequency control,it could make the motion speed increased smoothly.The test results show that the range are 0～460 mm,0～12 m/s,0～5 000 m/s2 for displacement,velocity and acceleration,the error of the velocity and acceleration is less than 1%.The apparatus can be used to calibrate the motion test equipment.
