선박 디젤엔진용 로터 캡의 구조해석 연구

Abstract

Roto cap is usually used to diesel engine, especially, big-sized diesel engine such as ship, power plant and so on. Intake and exhaust valves are essential parts of diesel engine and thus roto cap is one of the most important parts of intake and exhaust valves. Roto cap consists of body, disc spring, spring & steel ball, retainer and stop ring. In this study, the body and disc spring in parts of roto cap were simulated using static structural analysis. The purpose of this study is to achieve the data for designing and improving the roto cap. As the results, the body of roto cap showed safety factor of 6.3 in even 2 times of 1370N(target load) and the disc spring showed safety factor of 4.9 in 2370N load.
