This paper presents a new test system that combines a brake inertial dynamometer with a multi-axis vibration test stand. In addition, the system reproduces data collected directly from road tests, rather than prescribed or random data. Several areas of NVH work on wheel-end components can benefit form combining the effects of vibration and dynamometery without including the necessary remaining vehicle parts or the uncontrollable aspects of vehicle road or track tests. This paper addresses the design, assembly, operation, and success at reproducing road data on the Road Load Dynamometer. This system reproduces road data accurately, with greater repeatability, and with the added benefit of greater accessibility to components under test than road or track tests.
