Application of Visual Basic-based CATIA parametric modeling in the structural design of control arms

In response to the current challenge of design efficiency faced by companies, this study focuses on the design process of the control arms in the five-link rear suspension. By summarizing the common structural types of control arms and their corresponding key design parameters, Visual Basic and CATIA parametric modeling are applied for secondary development. This approach enables the rapid structural design of control arms and facilitates quick model updates during the design iteration process, significantly reducing modeling time, effectively improving design efficiency, and laying the foundation for intelligent design development systems.
