Studying the Stress Analysis in Leaf Spring by Finite Elements Method

Abstract

Light truck is considerably crucial for all the world economic growth since it was used in transportation for various kinds of commodities. Leaf spring is the most admire alternative utilized in the suspension system of this specific truck due to their low production cost, reliability and maintainability. In this, study a rational technique to design leaf spring for light truck is investigated. Simulation resembles to constrained condition when mounting on the vehicles were undertaken to examine the stresses distribution for each leaf. In this research the leaf spring is used on light truck with following information: Number of leaves equal five, Thickness of each leaf equal 10mm, length of distance from vertical line that divides the leaf spring to two equal parts, to one end of side of leaf spring, varies from (500 to 1000) mm, Radius of bow- shaped leaf spring varies from (1250 to 3000) mm and constant load applied on the first leaf equal 1000N on each side. The number of cases studied equal 24 case. The finite element method was applied as a method of analysis to examine the stress distribution for each leaf.
