In the research of vehicle dynamics various specialized test rigs are designed for specific elements or systems analysis. Expecting the reliable results all possible uncertainties and side effects should be known in advance. In this paper the analysis of special designed quarter car test rig is presented before its further use in wheel/tire, suspension or its complex research. After explaining the construction, its operation and application an experimental modal analysis and validation of test rig with on-road driving was done in order to find out any uncertainties. Different performance in separate frequency ranges of specific construction locations is identified. This is explained by the influence of unsymmetrical inner frame, suspension side mounting and wheel rotation dynamics. Finally further research possibilities using designed test rig and its options for vehicle components and separate systems including control strategies are presented proving the importance of reliable dynamic tests in laboratory conditions before on-road driving.
