Abstract

The invention discloses a test bench. The test bench includes a supporting system and a swing hammer system hinged to the supporting system; the swing hammer system comprises a swing rod portion and a swing hammer portion; the swing rod portion includes a first swing rod and a second swing rod; at least one first swing rod and at least one second swing rod are adopted; the swing plane of the first swing rod and the swing plane of the second swing rod are parallel to each other and are not overlapped with each other; the swing hammer portion includes a large swing hammer and a small swing hammer; the large swing hammer is connected with the bottom of the first swing rod and the bottom of the second swing rod; and the small swing hammer is connected with the bottom of the first swing rod or the bottom of the second swing rod. According to the test bench, the large swing hammer and the small swing hammer can be installed selectively according to test types; when simultaneously acting, the first swing rod and the second swing rod can be connected with the large swing hammer, so that an impact test of a front bumper and a back bumper of an automobile can be carried out; when acting alone, the first swing rod or the second swing rod can be connected with the small swing hammer, so that a free impact test can be carried out, and thus, the needs of different test environments can be satisfied.
