Vehicle Durability Simulator (VDS)

The VDS consists of a 6-degree-of-freedom spindle-coupled MTS 329LT test rig (fig. 74). The intent is to provide laboratory-based simulation of off- and on-road shock and vibration testing. Structural components and subsystems on 2-axle trucks up to 26,000 lb can be tested 24-hrs per day with precise control of the test scenario. The simulator can also be used as a kinematics and compliance measurement system to support vehicle modeling initiatives.

The strengths of the VDS are:
Accelerated durability testing of automotive systems, subsystems, and components (suspensions, computers, wiring, plumbing, chassis).
Troubleshooting and diagnosing component fatigue failures.
Vehicle model development.
