Suspension Springs-Experimental Proof of Reliability under Complex Loading
Fatigue strength of suspension springs in service life is subject to numerous influences.Besides the mechanical loading,determined by the kinematics of the suspension system,road conditions and driving maneuvers,fatigue strength of suspension springs is vitally affected by material properties,coating and environmental influences.Typical failure modes of suspension springs and their causes can be divided into several groups like static and cyclic loads,geometry and dimensions,manufacturing influences,mechanical defects of coating or steel surface,corrosion,fretting corrosion and imperfection of steel purity.This paper covers the influence of mechanical loading taking into account the influences of the kinematics of the suspension system,environmental conditions and steel purity.This leads to a comprehensive experimental validation strategy for suspension springs.Also statistical effects are discussed that have to be taken into account for a safe proof out.
