Design, Analysis and Optimization of a Lightweight Vehicle's Leaf Springs

In recent years, the automobile industry has primarily concentrated on reducing weight and improving ride quality. Because composite materials have a high strength-to-weight ratio, strong corrosion-resistance, tailorable qualities, Steel leaf springs are being phased out in favour of automotive industry. Three strategies been investigated to reduce vehicle weight: rationalizing body structure, using lightweight for parts, size. This study describes static dynamic analysis steel 55Si2Mn90 parabolic as well consisting E Glass fibre, Carbon Kevlar fibre. The goal this is examine load-carrying capability, stiffness, reduction springs. Dimensions an existing spring light commercial vehicle's taken. terms stress developed, comparison was made between fiber spring, after optimization, 45.67% lower than other superior riding quality typical with equal design criteria.
