A Review of the Application of CAE Simulation Technology in Mechanical Structural Optimization

Abstract

As mechanical systems evolve toward lighter configurations and improved reliability, the drawbacks of traditional structural design methods, which rely heavily on physical tests, have become more evident, particularly in terms of time-to-market and cost control. Computer-Aided Engineering (CAE), as an important virtual simulation technology, employs Finite Element Analysis (FEA) as a core method to provide technical support for enhancing mechanical system designs. This research offers a thorough examination of three crucial applications of CAE simulation in structural optimization: stress analysis, vibration analysis, and thermal performance analysis. It also looks into the usage scenarios of two prominent simulation tools, ANSYS and Abaqus, emphasizing their individual advantages. Based on this and integrating real-life applications such as mechanical components and marine structures, this paper examines and emphasizes the practical value of CAE technology in structural optimization. The results show that CAE simulation plays a vital part in optimizing the development process, reducing testing costs, and significantly enhancing the accuracy and reliability of structural engineering. Meanwhile, the development of emerging technologies, such as multiphysics coupling analysis and AI-assisted simulation, provides new directions for the application of CAE in addressing complex engineering problems.
