Study on Corrosion Fatigue Test of Vehicle Suspension Springs

Abstract

Corroion fatigue test of vehicle suspension springs is performed in several test condition. Each test springs are compared with used springs that is collected from field. Then most suitable corrosion fatigue test condition is find out. That is repetition of followings:
Dipping in salt water, Loading of cyclic stress, Drying in atomosphere with dead load.
This test procedure is able to simulate the field Corrosion circumstances and shorten test period.
