Abstract:-Even being one of the oldest suspension components, leaf springs are still frequently used, especially in commercial vehicles. The advantage of leaf spring over a helical one is that the ends may be guided along a definite path as it deflects to act as a structural member in addition to energy absorbing device. The main function of this is not only to support vertical load but also to isolate the road induced vibrations. It is subjected to millions of load cycles thus leading to fatigue failure. The present work attempts to describe the theoretical design considerations that are used during the design and analysis of leaf springs and also to analyse the theoretical safe stress value and its corresponding pay load for a typical leaf spring configuration of TATA-407 (Light Commercial Vehicle). Hence, the calculated outcomes are described in the later part.

Keywords : Leaf Springs, Deflect, Fatigue failure, Analysis, Safe Stress Value, Payload.
