Nonlinear elements are used when a mechanical system has different performance requirements according to its positions. Piecewise linear system is widely used to investigate and to approximate nonlinear elements. So far, just springs with constant stiffness were used for passive, active or semi-active RFC (reaction force compensation) systems. In this paper, we developed an adjustable passive RFC...
Residual vibration of the system base due to the rapid acceleration of a motion stage may significantly reduce life span and productivity of the manufacturing equipment. Although a passive reaction force compensation (RFC) mechanism was developed to reduce the residual vibration of a linear motor motion stage, the passive RFC cannot adjust its dynamic characteristic against the motion profile variation...
