Abstract
The interaction of the dynamic forces and moments introduced into the rotating wheel when driving through bends, over pathols or when suddenly braking is of great importance for the design and validation process of a new car. Due to increasing requirements on the components, due to shorter deeloping periods and because of the product reliability requirements a cost-effective, quick and accurate measurement of the forces under operating conditions is necessary for the automotive industry as well as for its suppliers, who are increasingly responsible for the development of their products. Instead of the instrumentation of suspension components as load trnsducers, today measuring wheels or hubs are used which, however, are quite heavy, not very accurate and need elaborate calibrations and computations. With the newly developed VEhicle LOad Sensor (VELOS) these deficiencies are overcome. Examples of road load data aquisitions comparing the results from VELOS with those of axle transducers under different maneuvers are presented. The effect of the location of the sensor in the suspension system is demonstrated for driving over an obstacle and on rough roads. Examples of VELOS for passenger and sports cars as well as trucks are described.
