The reciprocal load described on the piston after the spread and even compressed by all rotations, the master stroke undergoes tremendous stress. The other pistons are fixed to the rings around the end of the master chain. One piston is connected to a master rod in which the crankshaft can be mounted directly. In a radial motor the cylinders are connected with a master rod. Since the use of turbine engines radial engines were typically used for a number of aircraft. Radial Engine is an interconnecting motor design with the cylinders rising from a central crankshaft as well as from a wheel in the up and down direction. Keywords Aluminum Alloy, ANSYS R 14.5, CATIA V5 R20, FEM, Master Rod, Structural Steel. Master rod is modeled by FEM type of design approach to improve the fatigue life of the master rod that is used in Radial engine. Results are obtained, the stresses developed in master rod under static loading and different loading conditions of tension at the crank end & piston end of master rod. Harmonic analysis is carried out to find the various plots of frequency and amplitude for aluminum alloy & structural steel. The model is simplified in ANSYS by using the pre- processor. The model is designed in CATIA V5 R20 and translated to ANSYS R 14.5. In radial engine the pistons are connected for the crankshaft of master and slave (articulating) rod assembly.
