By using our patented High Power Shaker in test bench construction for Squeak and Rattle analyzes, disturbing noises can be detected and eliminated in good time.
The use of accelerometers mounted on the bodywork via magnets means all movements of the vehicle can be recorded and, hence, a so-called ‘Drive File’ generated during a real test drive over the defined rough stretch of road.
The use of HPS now makes it possible to induce the excitation recorded on the test track into the vehicle under laboratory conditions. The accuracy of the road profile simulation here is almost 100%. The advantage of the simulation is that there are no distracting secondary effects such as wind, engine or rolling noises.
A further advantage is the exact reproducible of the journey – as often as you like. This means all relevant disruptive noises can be detected and appropriate preventive measures taken in good time ahead of the start of series production.Learn More
