The Automobile Design Element Fatigue Life Modeling Due To Its Dynamic Model

The finite element method (FEM) analysis was conducted for the structural element of the automobile suspension during variable loading, taking into account the different nature of the road surface. Loading spectra on this construction were obtained based on its dynamic model made in FRUND program. A finite element calculation of the structural element was made using the obtained load spectrums for different types of the road surface with the calculation of the predicted service life. The possibility of replacing the material of this construction with a cheaper one, which provides the necessary strength and fatigue properties of the structure, is shown. The possibility of replacing the material this construction for cheaper materials providing the required strength and fatigue properties of the structure was shown.
