Abstract
For a time and cost effective testing a procedure is worked out to prove the fatigue life of passenger car suspension components. Using a generalized multiaxial load programme, fatigue behaviour of individual suspension components should be evaluated before the load data of service measurements are available. The procedure is based on a generalized load programme, which takes into account all decisive loading conditions and a representative customer usage. The load programme structure is divided in individual, physically different load sequences and allows an easy adaptation for varying vehicle parameters and eventually usage conditions. The procedure is described, the advantages and restrictions discussed and results of some tests presented. Furthermore there is introduced the application of a new developed measuring data aquisition and recalculation of multiaxial stress states by means of strain gauge rosettes, digital amplifiers and a personal computer.
