Stress and Fatigue Life Simulation of Camshaft with Structural Static ANSYS Approach

Abstract:

The failure occurred in the camshaft of the minibus vehicle after 14 years of use and a failure analysis was carried out to find the cause. The purpose of this paper is to simulate a failed camshaft by evaluating stress and fatigue using the ANSYS structural static approach to find the cause of the failure. Camshaft meshed with a size of 5 mm for the outer part of the fracture and 3 mm on the fracture. The load given is force (1400 N) and torque (113 Nm) and the support is fixed support on the second bearing. The stress shows that the applied load does not because fracture based on the theory of maximum normal stress and Mohr's criteria, the location of the highest and lowest stresses is not in the fault area, and fatigue life without defects produces infinite cycles or will not fail, and fatigue life simulation with defects results in a reduction in life. Based on these parameters, failure is caused by defects in the fractured part with an indication of the location of the fracture beyond the greatest potential for fracture and lower fatigue life.
