This paper describes the development of a load sensing trolley for frontal offset testing, to be used as a research tool in the field of compatibility assessment. The main specifications of the trolley, mass, CoG location, and inertia properties, are based on European and U.S. vehicle geometry databases. The influence of different mass and inertia properties was studied using a trolley model and vehicle models in numerical simulations. Based on this information and for research purposes, it was decided to make the trolley mass adjustable between 1300 kg and 1800 kg, with tunable inertia properties within realistic limits. The trolley was designed to be equipped with the progressive deformable barrier (PDB) as a deformable element. The PDB was chosen for its stability and its ability to allow a barrier face deformation measurement in order to evaluate the aggressiveness of cars. To study the potential of additional force measurements in MDB tests, the trolley is also equipped with a lightweight high resolution strain gauge loadcell wall in front of the trolley, just behind the deformable element. In total 48 strain gauge load cells of 125×125 mm2 are mounted in 6 rows and 8 columns to the front of the trolley. The LCW is equipped with a built-in data-acquisition system. With the first prototype trolley, several calibration tests were performed and it was concluded that the developed trolley is a good working research tool. The future work with the trolley will concentrate on the development and evaluation of a Mobile Progressive Deformable Barrier test procedure, based on the current draft PDB protocol. |
