It is important to eliminate the non-linear spring characteristics for positioning accuracy as like as the mechanical hysteresis characteristics. So that, the characteristics has to be analyzed to improve the dynamic performaces. At first, the "Non-Linear Spring Test Unit" is developed, which consists of two linear spring characteristics parts and mass. The magnitude of Non-linearity is defined which evaluates the influences on these dynamics. Then these influences are tested using this unit, it is proved that the non-linear spring characteristics make worse on positioning accuracy at the mechanical resonance frequency, and the allowable non-linear spring magnitude can be quantified as like as the mechanical hysteresis characteristics.
