Our range of extreme low noise N.V.H. Chassis Dynamometer systems have evolved and acquired techniques and capabilities previously only demanded in “high accuracy” emission test systems.
With continuous development of motor vehicles comes the demand for ever-improving product refinement. An increasingly significant area of this important work is passenger safety and comfort. The measurement and evaluation of vehicle noise, vibration, and harshness levels is subject to the variations in road and climatic conditions. By using a chassis dynamometer within a semi-anechoic chamber, the difficulty in monitoring these parameters under controlled conditions an be overcome.
Hofmann produce specialist chassis dynamometer designs which allow investigation of NVH levels whilst the vehicle is running under accurate and repeatable road load simulation, speed, force, or acceleration control.
