NVH Chassis Dynamometer

Overview

The NVH Chassis Dynamometer is used to evaluate a wide range of vehicles, from small passenger cars to light trucks, at up to 400 kph. The system can be configured with one, two or four rolls, with each axle, or each individual roll, driven by a motor. The drive motor(s) and power equipment can be isolated in a separate room, or in noise enclosures. The rolls are completely enclosed, except for the running surface in the room above, keeping background noise levels low. An automated wheelbase adjustment system accommodates a wide range of wheelbases on multi-axle systems. The dynamometer can be configured with a noise and vibration evaluation package, a hemi-anechoic room, an environmental control system, an engine cooler and vehicle tie down straps. The size of the rolls, their surface treatment, the allowable load range and other parameters can also be customized. A dedicated noise analyzer, controlled by ProLink software, captures and displays NVH data.
