| Abstract: | Nonlinear dynamic properties of super magneto s trict micro-actuator with asymmetry piecewise linear stiffness are analyzed. Th e effect of asymmetry piecewise linear stiffness of disc spring on nonlinear pro perties of micro-actuator is discussed. Based on the results of theoretic analy sis, we developed a super magnetostrict micro-actuator which can be used in pr ecision machinery. |
