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.
