Stress Analysis Of Rocker Arm Of Internal Combustion Engine

摘要

The effect o f total force i.e. gas pressure, inertia force and initial spring force acting on the existing rocker arm is evaluated. It is found that the maximu m stress is occurred at the push rod side end. For optimizatio n the various models of rocker arm are developed, keeping its weight constant. The effect of total force on this various models are evaluated. The model showing less stress is found suitable as compared to other models. Geometric models are developed in software Pro-E and for analysis software ANSYS 11 is used
