Technology for Fatigue Life Prediction of Mechanical Components using Multibody Dynamics

다물체동력학을 이용한 기계 부품의 피로수명 예측 기술

Fatigue life prediction of mechanical components is necessary to develop new products, which is very expensive and time-consuming. This paper reviews technologies proposed for computation of dynamic stress in mechanical components. The methods based on multibody dynamics are considering more real operational conditions than other methods. The technology for fatigue life prediction without the prototype for experiment results in cost and time saving. This technology can be applied to design of various mechanical components like carbody.
