Abstract

The failure of leaf spring fatigue is to be determined the analysis of life prediction. By using NX Nastran materials various analysis were observed in the selected software with suitable material. In the system of vehicle suspensions Leaf springs are used most in common which are limited to varying cycles stress to millions thus eventually leads to failure of fatigue. High definition value and high elastic limits are presented in spring material possess maximum strength with fatigue effects and shocks. Weight reduction is the main focus in automobile manufactures in direct to preserve natural assets and power of economic in the current scenario. By inducting an advanced material weight reduction can be achieved thus resulted in improved manufacturing process and design optimization, along with better fuel efficiency and affirmed riding qualities. Without reducing the load carrying the capacity and stiffness composite materials were introduced and reduced the weight of leaf spring. The weight ratio of composite material which has elastic strain energy storage capacity is compared to the steel and multi-leaf steel; it also tends to be replaced by composite springs of mono-leaf. The savings of substantial weight which was offered by composite materials are cost effective in terms of counterparts of steel.
