FINITE ELEMENT ANALYSIS OF A LONGITUDINAL TRANSMISSION SYSTEM

Abstract

This paper addresses how a longitudinal transmission system of a car could be analyzedusing Autodesk Inventor software. The longitudinal transmission, also known as a driveshaft or cardan shaft, is a system used in rear-wheel-drive or all-wheel-drive vehicles where power is transmitted from the engine to the rear axle or to both axles. During the operation of the longitudinal transmission, various loads can lead to the wear and tear of the universal joints, resulting in failures or even the destruction of the system. To prevent these issues, we considered it necessary to analyze the modelled driveshaft using Inventor based on von Mises stresses and the safety factor. The material used in this study is cast steel with the following properties: Mass Density 7.85 g/cm³, Yield Strength 250 MPa, Ultimate Tensile Strength 300 MPa, and Young's Modulus 210 GPa. The results obtained for different angles of inclination of the universal joint axes lead to the conclusion that the positioning of the driveshaft significantly influences the durability of the longitudinal transmission system.
