ABSTRACT
This chapter provides a notion about the usefulness of using modeling and virtual modeling in developing a prototype. Some examples are also used to demonstrate the idea. A mathematical model can be analytical, numerical, or a fuzzy model, and it can also be a static, quasi-static, or dynamic model. Selecting model fidelity is a trade-off decision between model descriptiveness versus model construction and resolution determination time. Conservation of momentum states that in the absence of external forces, a system will have constant total momentum. It is commonly used in collision models. Many types of commercial software are excellent virtual prototyping tools, and often they start with a CAD model to define the product geometry. Virtual prototyping can be used for a designer to interact with the product before it is actually created. Advances in virtual reality and simulation technologies have demonstrated the capability of performing significant product trade-offs in a virtual environment.
