The Use of QFD and TRIZ in the Component Mathematics Modeling for Virtual Durability Simulation

The process development of products due to raised amount of information to be manipulated is characterized for its complexity. To assist the product project innumerable tools exist: CAD (Computer Aided Design), CAE (Computer Aided Engineering), CAM (Computer Aided Manufacturing), QFD (Quality Function Deployment) and the TRIZ (Theory of Inventive Problem Solving) and others.

This article presents an application of QFD (Quality Function Deployment) and of the TRIZ (Theory of Inventive Problem Solving) to assist professionals of the CAE in the design components in the computational simulation of durability. It also presents the differences between the mathematical modeling using the attachment points of the part used in this paper in two different ways. To evaluate the results of the application of the proposal, a critical analysis of the modeling used currently and the proposal will be carried through.

To carry through the computational simulation it was used MSC_Nastran software 2004 R2, Sol 103 (normal modes with option: design sensitivity - modes) and Sol 112 (modal transient response). [17].
