Test Study on Fatigue Property of Sheet Steels for Automobile

Abstract:

Article Preview

Automobile body sheets mainly resist impact and pressure. However, the fatigue property is one of the main factors with regard to properties of sheet steels. Continuous vibration happens all over the sheet steels (especially chassis) while the vehicle is in motion. And the fatigue property becomes particularly important in the condition above. Fatigue tests are conducted to four kinds of thin sheet steels for automobile in this paper. The fatigue lives of samples from sheet steels are obtained according to the various stresses. The inferior limits of fatigue life and the inferior limits of fatigue strength under the higher stresses are acquired by the computation of fatigue data. Furthermore, the test results show that there is a certain relationship among the tensile strength, yielding strength and inferior limit of fatigue strength for these sheet steels. This paper is of certain reference significance for other similar test.
