Analysis viscoelastic properties of fiber-reinforced composite spring for the all-terrain vehicle

Abstract

For today’s composite materials have many advantages over steel materials. The composite materials take the main part in modern automobile constructions. Suspension system is the main automobile part. Components of suspension system are made of metal. Therefor suspension system have a high weight that have a negative effect for all of vehicle especially for vehicle dynamics and stability properties. The main part of suspension system is a spring element. Coil springs are the most widely used spring type for independent wheel suspension for trucks and passengers vehicles. Using composite springs can less vehicle weight especially less unspring masses. It is one of the main features of composite materials. Another feature is viscoelastic properties and hysteresis effect. That can be give excellent noise and vibration properties for vehicles.
