초록

자동차 조향장치의 볼 조인트의 더스트 커버의 밀봉성과 응력 평가를 위하여 비선형 요한요소해석을 수행하였다. 주름형상과 항아리형상의 두 종류의 더스트 커버에 대하여 조립상태와 작동상태에 대하여 해석을 수행하여, 최대응력과 리브에서의 접촉응력 결과를 평가하고 비교하였다. 또한 작동상태에서의 몸통부 응력과 리브의 접촉응력이 조립상태 대비 증가하는 정도를 평가하였다. 해석 결과로부터 두 종류 모두 밀봉성이 우수한 것으로 확인되었으나, 상대적으로 최대응력이 작은 주름형상이 항아리형상보다 더 우수한 것으로 나타났다.

A nonlinear finite element analysis is performed to evaluate the sealing capability and stress of dust covers for the ball joint of an automotive steering system. The analysis is performed for two types of dust covers: wrinkle type and pot type. The assembly condition and operation condition are analyzed, and the maximum stress and contact normal stress at the ribs are evaluated. It is confirmed that the sealing capability of both types is fairly good, but the wrinkle type is better than the pot type in terms of the maximum stress.
