Integrated Wheel Dynamometer Technology for Vehicle and Bench Testing

In recent years wheel dynamometer measuring systems,using strain gauge and quartz technologies, have been optimised and are mature now. For specific fields of application the use of sensors based on either of the two measuring technologies would be the technically optimal choice. For technical, practical and economic reasons often two systems in parallel couldn't be used and thus limitations needed to be accepted. In order to overcome these limitations Kistler integrated sensors with both measurement technologies into one product family. Using results from practical applications and investigations the paper describes the new potential to get better test results faster. Kistler continously works towards a better integration of engineering processes (numerical simulation, testing on benches and in the vehicle).
