Finite Element Analysis of Universal Joint and Propeller Shaft Assembly

摘要

The power transmission system is the system whichcauses movement of vehicles by transferring the torque producedby the engines to the wheels after some modifications. Thetransfer and modification system of vehicles is called as powertransmission system. The power transmission system of vehiclesconsists of several components which encounter unfortunatefailures. These failures may be attributed to material faults,material processing faults, manufacturing and design faults, etc.Maintenance faults and user originated faults may alsoresponsible. Propeller shaft and the universal joints form theimportant links that help in transmitting power from the engineto the wheels. In this study, analysis is being performed on theuniversal joint yoke and the propeller shaft. In the universaljoint yoke, certain modifications are made in the existinggeometry and analysed for the identical loading and boundaryconditions as in the reference paper from which the problem hasbeen taken. In case of propeller shaft a comparative study hasbeen made between two shafts differing in their material,keeping in view the possible weight reduction that can beobtained without affecting the functionality of the shaft. Both thecomponents are analysed in ANSYS and the results arecompared.
