Reliability testing of components is an important part of the development process for heavy trucks. Components such as cabins, fuel tanks and mudguards are tested as subsys-tems, e.g. without the complete vehicle, in test rigs. Reference signals of sensors are obtained through measurements on the complete vehicle in service conditions. The test rig is designed and controlled so as to reproduce the reference signals. It is generally held that a good corre-lation between the reference signals and the corresponding test signals indicate that the test reproduces the damaging process of the service conditions. Due to the differences between the test setup and the complete vehicle it is not possible to perfectly reproduce neither the ser-vice conditions nor the reference signals. It is proposed to use a modal filter to estimate the modal displacements, and to control the test rig so as to reproduce the estimated modal dis-placements. The modal filter has been applied to an industrial test of a truck cabin.
