The simulated camshaft is used in the 1NZ-FE engine, and the author uses the method calculated, simulated by finite elements through Abaqus software. After building the camshaft blueprint, the input data including external forces and materials which are set and entered into the software. The results obtained include comparisons between the recorded stress and displacement and the acceptable values, in order to evaluate and draw conclusions upon the durability. Additionally, the results from this study are also the basis for durability testing when designing in order to reduce the cost of testing components. At the same time, it can also be a reference for mechanical component designers and manufacturers in various fields of mechanics, especially in the field of dynamic mechanics.
