Leaf springs are unique kind of springs used in automobile suspension systems. The benefit of leaf spring over helical spring is that the ends of the spring may be leaded along a definite path as it deflects to act as a structural member in addition to energy absorbing device. The main work of leaf spring is not only to give support to vertical load but also to isolate road induced vibrations. It is subjected to millions of load cycles leading to fatigue failure. Static analysis gives the safe stress and with corresponding pay load of the leaf spring and also to research the behavior of structures under practical situations. The existing work attempts to examine the safe load of the leaf spring, which will represent the speed at which a comfortable speed and safe drive is available. A typical leaf spring configuration of TATA-407 light commercial vehicle is selected for research. Finite element analysis has been carried out to determine the safe stresses and pay loads.
