Design Analysis & Fabrication of Test Rig for Piston Pin Fatigue Life Assessment

Every component has certain lifetime in order to increase their lifetime different manufacturing methods are to be used. The studies indicate that the greatest stress appears on the upper end of the piston pin and this stress concentration is one of the mainly reason for fatigue failure of piston pin. In order to increase the fatigue life, automobile industries tries to fabricate the piston pin in various methods. Since the pin is subject to fluctuating kind of load during its service condition, the estimation of the life of the piston pin is very much essential. Also this exercise help us to identify which method of production has yield more life. Our main objective is to design and fabricate a test rig for fatigue test of piston pin. The fixtures for simulating actual service condition is modeled and analyzed using CATIA and ANSYS software' and based on the results the dimensions for each component are evolved. Also proved that the fixture developed in this works satisfactorily and the given piston pin serves for more than 300000 cycles for the given loads. R. Sampathkumar | P.
