Car white vehicle body structure static angular rigidity testing system

The utility model discloses a with bodywork structure static rigidity test system for passenger car. A restraint device (41) comprises a front pedestal assembly (4) and a rear pedestal assembly (2); a servo loading device (42) is equipped with a flexural rigidity loading device (44) and a torsional rigidity loading device (45) for loading on the tested bodywork (3); a data acquisition and processing system is equipped with a bodywork bending deflection measuring device (46) and a bodywork torsion angle measuring device (47). Comparing with the current passenger car bodywork structure flexural and torsional rigidity testing technology and equipment, the technique scheme achieves the advantages of better versatility, simpler operation, shorter time, lower labor intensity, higher efficiency in detection and test, more accuracy in test data, higher precision, higher reliability and higher economic benefit.
