고온하에서의 스프링의 피로특성에 관한 연구
A study on fatigue characteristics of spring under high-temperature
초록
The fatigue characteristic study of a Pony Coil spring is performed by considering the tropical service conditions in the range of 50.deg. C through 150.deg. C. The experiment results of the static and dynamic characteristics of the test pieces agreed with the result of the strain analysis by wittricke's method. The strain energy value is increased as temperature rises. An increase is 1.58% at 100.deg. C and 2.26% at 150.deg. C after fatigue tests. The elastic strain is also decreased as temperature rises.
