Design and Analysis of Leaf Spring Using Ansys

Abstract

Abstract: The leaf springs are different spring styles used for automotive suspension systems. In addition to the use of energy absorption equipment, the ends of the spring can be pointed in a certain direction as it deflects as a structural function. Not primarily supporting vertical loads but isolating road-induced vibration is the principal feature of leaf spring. The present research aims at studying the safe load of the leaf spring, showing how easily an easy, safe driving speed is achieved. A standard TATA-407 light commercial vehicle leaf spring configuration is chosen. Finite element analysis for safe stresses and pay loads has been done. Conventional materials and alternative materials in spring construction used in the present work have been studied. Computer aided designing (CAD) is being widely used in different industries for product testing and manufacturing, this paper consist of design and analysis of leaf spring using ANSYS 19.2. Static structural tool has been used of ANSYS. Leaf springs are used in heavy load vehicle where load is much larger than in passenger vehicles, they are used in vehicles which are limited to varying cycles stress to millions thus eventually leads to failure of fatigue. High elastic material springs are used which possess maximum strength and fatigue effects. Weight reduction is one of the major concern while designing a vehicle as it helps in design optimization and fuel economy’s three layer composite leaf spring with full length leave. E-glass/Epoxy composite material has been used and is compared with conventional steel leaf spring. After conducting various tests it is found that eglass/epoxymaterial is better in strength and lighter in weight as contrast with conventional steel leaf spring.
