The Finite Element Method Simulation of Rear Driveshaft Failure in Trucks

There was a failure in the truck’s rear driveshaft in the spline during the transportation of rock and sand in Aceh Besar, in Indonesia. Therefore, this research aims to analyze the causes of failures in the rear driveshaft of the truck by performing a finite element analysis (FEA) simulation. It was discovered that the standard for the shaft material is AISI 4150. Based on the results, the maximum shear stress was s 233.21 MPa, this has exceeded the allowable value of 80.7 MPa and shear stress Tresca which is 190 MPa. Furthermore, the Von misses shear stress analysis obtained is 426.2 MPa, which is above 179.13 MPa. The analysis of the stress intensity factor also obtained an average value of 27.7 MPa√m, which is more than the 10 MPa√m (KI > KIC) fracture toughness value, thereby triggering crack propagation to fracture.
