概要:

application/pdf<br />Journal Article<br />Since electromagnetic force is a function of the gap between two magnets, the spring constant has large nonlinearities with respect to the displacement. Hence, the spring constant varies significantly with the initial load. This implies that the linear control theory is not applicable in the range of large displacement. To treat a system with variable initial load and large displacement, the present … article presents a procedure for obtaining a linear spring by means of a repulsive-type actuator using permanent magnets and an electromagnet. The analytical expression for the linear spring is presented. Experimental tests were carried out, and the theoretical values are compared with the experimental results. 続きを見る
