This paper describes design and FEA analysis of mono leaf or single-leaf spring that consists of simply one plate of spring. The performance analysis of spring is under static loading condition. Due to the absorb and release property it is become a major factor in designing the leaf spring which is showing the replacement of steel springs with composite leaf springs. A current leaf spring is made up of a steel material which is having high weight, high corrosion, more noise and the property of material is changing when the load is acting and gives low natural frequency. Therefore, composite materials become the predominant alternative material for replacing the spring steels. The objective of this paper is to compare the load carrying capacity, strength and weight saving of composite leaf spring with that of EN45 steel leaf spring. The design constraints are stress, deflection and weight saving for comfort riding and enhancing durability of spring. Dimensions of the composite leaf spring are to be taken as same as conventional EN45 steel leaf spring used in TATA SUMO GOLD for rear suspension. A Finite element approach for analysis of mono leaf springs using ANSYS R15 software is carried out. Using CATIA V5R20 for modelling the leaf spring. The results are compared with the properties of EN45 steel and thermoplastic polyimide with 30% carbon fibre composite material.
