Abstract

Rocker arms are part of the valve-actuating mechanism. Over the years rocker arms have been optimized in its design and material for better performance. Durability, toughness, high dimension stability, wear resistance, strength and cost of materials as well as economic factors are the reasons for optimization of rocker arm. Various types of rocker arm used in vehicles and different materials used for making rocker arm are studied in this paper. Failure of rocker arm is a measure concern as it is one of the important components of push rod IC engines. Present work finds the various stresses under extreme load condition. For this we are modeling the arm using design software and the stressed regions are found out using Ansys software. Rocker arm is the important component of engine assembly in this paper we consider rocker arm and through the literature finite element analysis(FEA)in ANSYS is done for five different material viz. Aluminum alloy, chromium molybdenum, grey cast iron, HSS, structural steel. The result of ANSYS shows that structural steel is the best material for rocker arm. The result of software is validated experimentally by tensile test on UTM, brinell test on hardness tester and microstructural analysis.
