TESYS - Dynamometer - Chassis Dynamometer (LDV) - Noise, Vibration, and Harshness (NVH)

Our range of extreme low noise NVH chassis dynamometer systems have evolved and acquired techniques and capabilities previously only demanded in "high accuracy" emission test systems.  With continuous development of modern vehicles comes the demand for ever-improving product refinement. An increasingly significant area of this important work is passenger’s 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 asemi-anechoic chamber, the difficulty in monitoring these parameters under controlled manner can be overcome. TeSys produces a special chassis dynamometer design which allows investigation of NVH levels whilst the vehicle is running under accurate and repeatable road load simulation, speed, force or acceleration control mode.
