Abstract: | |
A leaf spring is a simple form spring commonly used for suspension in wheel vehicles. The automobile industry has shown keen interest for replacement of steel leaf spring with that of composite leaf spring. Since the composite material has high strength to weight ratio, good corrosion resistance and other thermal properties. The steel material is replaced with the composite material. A spring with constant width and thickness was fabricated by hand lay – up technique which was very simple and economical. The numerical analysis is carried via finite element analysis using ANSYS software. Stress, deflection and strain energy results for both steel and composite leaf spring material were obtained. The design and FEA analysis is of composite leaf spring made of glass fiber reinforced polymer. The dimensions of an existing conventional steel leaf spring of a light commercial vehicle are taken for evaluation of results. |
