A Correlation Study of an FEA Method Developed for Heavy Duty Driveshaft Applications

Abstract

The driveshafts are responsible for transmitting power and rotational movement from the engine to the rear axles. In order to fulfill high torque transmission requirements, driveshaft components are generally produced from steel by hot forging process. For steel components, reduction of the weight is limited by geometrical alterations due to boundary conditions, functionality requirements etc. For this reason, verification method of design iterations must be conducted accurately. Although verification on physical component is much reliable, regarding high material, die, tooling and machining costs an alternative verification method is needed. Generally finite element analysis (FEA) is preferred as design verification method. The major phenomenon is to build the simulation as similar as possible with real conditions in order to have accurate results. In this study, an FEA method was developed for design verification of heavy duty driveshafts. The results from FEA analysis of heavy duty driveshaft were compared with the results from the bench tests and a correlation study was conducted to reveal the consistency of developed FEA method.
