Automotive Stabilizer Bar System Design and Reliability

Stabilizer bar systems are present in almost every automobile sold today. They are used to tune ride, handling, and steering. This paper surveys the design alternatives for stabilizer bars, bushings, and links. It covers their function, performance, and basic design considerations. In addition, the paper provides an overview of stabilizer bar system reliability planning: ideal function, error states, noise factors, control factors, noise factor management, and validation testing are discussed.
