Design and Static Analysis of Sandwiched Leaf Spring with Hyper-elastic Material

Manav Kumar , Dheeraj Kumar and Sharifuddin Monda

Abstract

To satisfy the needs and demands of customers, there are constant developments in automobile suspension systems to improve riding comfort. The vibration and impact caused by road irregularities are absorbed by the leaf spring. In this work, rubber is sandwiched between the metal leaves to configure a new leaf spring to provide better riding comfort and lighter vehicles. The leaf spring is modeled in CATIA V5 and static structural analyses are performed in the ANSYS environment. Different hyper-elastic models such as the Mooney Rivlin Model, Yeoh Model, and Arruda Boynce Model are used for analyzing the rubber material by curve fitting. Five different rubber materials, such as chloroprene rubber (CR), strene-butadiene rubber (SBR), carbon-filled natural rubber (CFR), and natural rubber (NR55) are selected for comparative analysis. According to the findings, a rubber-sandwiched leaf spring increases the total energy-storing capability of the leaf spring, resulting in improved riding comfort.
