Squeak & Rattle
By using our patented high-power shakers in test bench construction for squeak and rattle analyses, unwanted noises can be detected and eliminated at an early stage.
Acceleration sensors mounted on the vehicle body record all vehicle movements real test drive drive file .
Using our vehicle test bench, it is now possible to introduce the excitation recorded on the test track into the vehicle under laboratory conditions.
In addition to these time-history signals, random and sine waves be used for testing. The accuracy of the road profile tracking is nearly 100%.
A key advantage of the simulation is the absence of disruptive side effects such as wind, engine, or tire noise.
Another benefit is the precise reproducibility of the test drive , as often as required. Retrofitting the vehicle test bench into existing testing and production lines is also possible.
