Analisis kegagalan camshaft toyota kijang / Riduwan Prasetya

Abstrak
A failure happens within the camshaft of the minibus when the vehicle is in utilize. The camshaft was afracture within the bearing between the primary cylinder exhaust valve and the second cylinder suction. Thissimulation aims to find the causes of camshaft failure utilizing the finite element method with a staticstructural approach including simulations of deformation strain stress fatigue life (stress-life and strainlife) and cracks. The method used in this paper is the finite element method with a static structural approachby ANSYS software. The camshaft material is a gray cast iron designed using Solidworks. Pre-processingincludes meshing with a size of 3 mm. The value of loading force (1348.28 N) and torque (113400 Nmm)are fixed and the boundary conditions are varied. Processing includes the process of computation and postprocessing into a part that displays the results. The simulation results show that for all the deformation andstrain values that are in the elasticity area of the material the maximum and minimum stress which is belowthe strength of the material the location of the maximum values of deformation strain and stress is not atthe fault location. The simulation of fatigue life both in stress-life and strain-life results in infinite cycles which is above 106 cycles while the simulation of cracks results in a decrease in the cycle. Based on thesimulation results with the above parameters to the camshaft it was found that a failure was caused by adefect characterized by reduced fatigue life at the same loading conditions
