The invention discloses a test method for real object
crash of vehicle components and a test device thereof. The test method comprises the following steps: the vehicle components are fixed on a carrying trolley which can move on a track, the speed of the trolley is increased to a test value by traction with a drive
system before preparing for
crash an
impact wall; when the carrying trolley moves to a set position before the
impact wall, a trigger device is started to detach the drive
system from the carrying trolley, a test component and the carrying trolley are caused to
crash the
impact wall without drive power; a vehicle-borne acceleration test
system is arranged on the carrying trolley so as to
complete data acquisition in real time; and the trigger device triggers a
speed test system, an impact force test system and a high-speed camera system at the same time. The test method of the real object crash of the vehicle components and the test device can help measure
objective data in real time such as the impact force, a transient acceleration, component deformation and speed output at the moment of crash, and further can
record deformation sequence images of the components during the whole crash course so as to get scientific and exact analysis results.
