Parallel spring is usually adopted for a pricise positioning servo system. This mechanism has many resonances of higher order, therefore it is difficult to obtain a wide band and high loop gain servo system. This paper presents a new method to analyze a dynamic characteristics of the mechanism. Many parameters such as the dimensions of the leaf spring, the coordinates of a sensing point, and a force acting point are considered. By this method, it is possible to simulate the behavior of the mechanism and obtain the relations between the transfer function and above parameters. This analysis is verified experimentally to be reasonable. By utilizing the method, a simple servo system and a small-sized actuator with wide band frequency response are realized.
