Full Size NVH Brake Dynamometer

The GIANT Evo NVH is the largest dynamometer within the GIANT Evo family. It is a full-size NVH inertia brake dynamometer for basic and advanced NVH testing. It is used to test a variety of vehicle brakes and assemblies. This includes disc and drum brakes from small to large cars as well as brake systems of medium-sized SUVs.

The GIANT Evo NVH offers a whole range of functions for realistic and fully automatic NVH tests. Due to its various optional features it is able to meet special customer requirements also for sophisticated NVH investigations.

Due to its special design the GIANT Evo NVH is particularly suitable to perform NVH investigations with complete axle structures and suspension strut assemblies. Also basic performance procedures are feasible if the test brake is mounted to the test flange via a joint shaft as a brake disc, caliper and original knuckle assemblies. Furthermore, assemblies with a standardized reusable HORIBA machine knuckle and wheel bearing can be connected to the dynamometer.

Particularly with regard to NVH tests, the GIANT Evo NVH has two separate machine frames, one for the NVH testing station and the other one for the drive unit. Thus, the NVH testing station is designed with a maximum interior noise level of 55dB (A)*.

Due to the precise inertia simulation and state-of-the-art test brake control, investigations are conducted under realistic operating conditions. Therefore, the standard scope of supply includes a climatic chamber for performing climatic tests from -20°C up to +50°C (optional -40°C to 50°C). Depending on customers’ requirements, the NVH testing station can be either configured with a large testing station frame (3.5m x 3.5m outer frame dimensions) or with a smaller testing station frame (1.1m x 1.8m outer frame dimensions). The climatic testing chamber has the same size for both variants.
