Squeak and Rattle Performance Degradation and Prevention in a Vehicle Design and Development Process
Squeak and rattle is one of the major quality concerns in vehicle designs for customer satisfaction. Although a significant amount of work has been conducted in squeak and rattle detection and prevention for new (low mileage in service) vehicles, relatively little work has been done in squeak and rattle degradation and prevention for high-mileage-in-service vehicles. This paper is a first attempt in the automotive industry to systematically address root cause analysis of both low-mileage (or short-term) and high-mileage (or long-term) vehicle squeak and rattle degradation and corresponding prevention strategies.
