초록
In this study, the design of the lower arm, a type of suspension for a 4 wheel drive vehicle, was dealt with through structural analysis. In the case of the existing lower arm, cracks occurred in the neck, so it is necessary to reduce the maximum stress in order to extend the life of the analysis model. Based on this, various design changes were made, and the maximum stress generated was compared through structural analysis of each design change model. For structural analysis, a unit load (1N) was applied in the vertical direction to the lower arm model, and the results were analyzed relative to each other. As a result of analysis through various design changes, case 3, a model in which the stress concentration applied to the lower arm was relieved, showed an increase in strength of about 51% compared to the existing model.
