Failure Analysis of the Lower Rear Ball Joint on the High-Mobility Multipurpose Wheeled Vehicle (HMMWV)

Abstract

Tests of the HMMWV M1037 S-250 Shelter Carrier conducted at Aberdeen Proving Grounds (APG) and the Nevada Automotive Test Center (NATC) have resulted in failures of the lower rear ball joints. A three-dimensional computer model of the HMMWV Shelter Carrier, including all suspension and steering components, was developed using the DADS methodology to calculate the position, velocity, and acceleration as well as the forces and torques at critical points on the vehicle and at suspension elements while the vehicle is negotiating the NATC course. The results give the magnitude of the forces acting on the joint and also provide the scenario of leading to the failure. The joint angle between the ball joint stud and the ball joint housing was calculated to determine if an interference condition occurred. Keywords: Simulation, DADS, HMMWV, Suspension, Ball joints, Dynamics.
