NVH
With continuous development of motor vehicles comes the demand for improving product refinement. An increasingly significant area of this important work is in passenger safety and comfort. The measurement and evaluation of vehicle noise, vibration and harshness levels, however, is subject to the variations in road and climatic conditions.
By using a chassis dynamometer within an anechoic chamber, the difficulty in monitoring these parameters under controlled conditions can be overcome. Froude Hofmann have many specialist dynamometer facilities which allow investigation of NVH levels whilst the vehicle is running under accurate and repeatable road load simulation, speed, force or acceleration control.
Froude Hofmann NVH chassis dynamometers are available in single roller, 4x2, 4x4 and independent configurations. The rollers are available from 1.8 m to 2.5 m diameter, running in hydrodynamic or rolling element bearings.
Main Features:
- Unique roller design
- 4x2, 4x4 and independent versions
- Hydrostatic or rolling element bearing designs
- Close coupled or remote motor designs
- Noise levels as low as 42dBA (no vehicle present)
- Data acquisition and monitoring
- Host file server and networking facility
