Behavior Modeling in Mechanical Engineering- A Modular Approach

Many engineering activities are confronted with the relation between shape and behavior. Modern ”state-of-the-art ” CAD systems can support a dynamic design process with flexible and unambiguous geometric modeling of artifacts. The finite element (FE) method is a general method to model and simulate physical behavior. CAD and FE integration enables numerical prediction of the physical behavior of artifacts. To deal with the complexity of modern products and the dynamic character of the design process, the integration must be addressed from both a systems and a process point of view. The models must thus be flexible, scaleable, and reusable. A modularized modeling approach based on four stages is proposed, and exemplified with behavior modeling of a turn-key grinding machine.
