Abstract

A test bench, comprising: a support system (100) and a pendulum system (200) hinged to the support system (100), the pendulum system (200) comprising a pendulum rod portion (210) and a pendulum portion (220), the pendulum rod portion (210) comprising at least one first pendulum rod (211) and at least one second pendulum rod (212), a swing plane of the first pendulum rod (211) being parallel to but not coinciding with a swing plane of the second pendulum rod (212), the pendulum portion (220) comprising a large pendulum and a small pendulum, the large pendulum being connected to the bottom of the first pendulum rod (211) and the second pendulum rod (212), the small pendulum being connected to the bottom of the first pendulum rod (211) or the second pendulum rod (212). The large pendulum or the small pendulum are selected for mounting according to a test type, the large pendulum may be connected for an automobile front and rear end bumper impact test when the first pendulum rod (211) and the second pendulum rod (212) act simultaneously, and the small pendulum may be connected for a free impact test when the first pendulum rod (211) or the second pendulum rod (212) acts individually, thereby satisfying different test environment requirements.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a combined pendulum test bench for automobile front and rear end bumpers and free impact tests. Background technique [0002] The front and rear protection devices of automobiles (including bumpers, airbags, etc.) are an important part of the automobile body. From the perspective of automobile passive safety, they play a decisive role in low-speed collision, pedestrian and occupant protection. [0003] According to the requirements of "National Standard for Automobile Low-speed Collision (GB17354)" and "Unified Regulations on the Approval of Vehicles with Front and Rear Protective Devices (Bumpers, etc.) (ECE R42)", large The small pendulum is used for the misuse test of the airbag and the free impact test for other self-developed products. [0004] The large pendulum test bench of the prior art can only be equipped with a large pendulum for the bumper impact test, but not a small pendul...
