Plastic Door Trim Design Process Study

Abstract

We live in an age of ever-increasing product complexity, rapidly evolving technologies and global competition for new and improved products more quickly with world class level of quality and reliability. To excel in the competition and reduce the design lead time product engineers use several techniques like optimization, Design of Experiments FEA and Rapid prototyping etc. Wall thickness of any component is a vital design decision that affects structural performance, material utilization, and processing costs. Protection, vehicle dynamics, aesthetics, and strength are all important factors to consider when designing the door assembly..Apart from the above, door trim should be designed to reduce BSR (buzz, squeak, and rattle) during vehicle operation. Stiffness is a critical engineering requirement that, if not met, will result in higher BSR levels and door trim part failure.
