Strength Evaluation of the Cylinder Liner of Low-Speed Marine Engine
대형 엔진 실린더 라이너의 강도평가
- Published : 2001.06.27
Abstract
Strength evaluation was carried out for the cylinder liner of a low-speed marine engine. Calculation of temperature distribution, nonlinear structural analysis, material test, and fatigue strength evaluation are briefly introduced in this paper. Strengths of five liner models are compared, and the effect of materials experiencing different heat treatment is evaluated. Structural analysis including boundary and material non-linearities was performed for axisymmetric liner models. High cycle (fatigue limit) and low cycle (fatigue life) fatigue analyses are carried out. As results, localized high stress was occurred next to the mount line. Maximum stresses are varied significantly with respect to different liner models and different materials.
