In recent years, enhancing computer-aided engineering (CAE) analysis is the most pressing issue facing companies seeking to implement development design that results in high quality and shortened delivery times. This paper presents an “Optimal CAE Design Approach Model” that can be used to reform the business processes associated with development design. The model consists of the following steps: (1) defining the problem, (2) conducting prototype testing, (3) visualizing the problem, (4) employing the CAE technological element analysis model, (5) conducting a two-dimensional CAE analysis, (6) conducting a three-dimensional CAE analysis, (7) carrying out a predictive evaluation, (8) optimizing the design, and (9) verifying the results. As a specific application for this process, the authors focused on the ongoing problem of bolt loosening at automakers, using the model to explain the loosening mechanism by analyzing the contact stress at the bearing surfaces in bolted parts and gain new knowledge.
