A Study on Design Method of the Cylindrical-Taper Section Coil Spring

등반경-테이퍼 소재 비선형 특성의 코일 스프링 설계 방법 연구

The coil spring is used in the suspension of automotive vehicles and small omnibus. Recently, it can be adopted hardening type spring which spring constant is accompanied by increasing displacement to increase passenger comfortability. One of methods which assert this characteristic is cylindrical-taper section coil spring. In this paper we calculate ideal spring characteristic curve from the given vehicle conditions, and show the design method of the cylindrical-taper section coil spring.
