Dynamic impact test equipment

Abstract

The invention discloses dynamic impact test equipment. The dynamic impact test equipment comprises a ground rail, a counterguard wall surface, a trolley, a traction device, a braking device, a cushioning device and a test recording device, wherein the counterguard wall surface is provided with a test sample piece. The trolley is arranged on the ground rail, can run along the ground rail and is provided with an impact device. The impact device can run together with the trolley, can slide on the trolley under the effect of inertia and then impacts the test sample piece which is installed on the counterguard wall surface. The dynamic impact test equipment can conduct a high speed dynamic impact test of automobile body components and parts and is simple in structure and low in cost.

Description

technical field [0001] The invention relates to a test device, in particular to a dynamic impact test device. Background technique [0002] In the process of safety development of automobile body structure, the performance of each body part usually needs to be tested through experiments. Components and Constraint System Components. [0003] The test methods include dynamic impact test and static test. Relatively speaking, the dynamic impact test can more accurately reflect the performance of parts. The existing dynamic impact test equipment for body parts is usually a vertical drop type. The free fall is accelerated, so that the impact block hits the body parts at a predetermined speed. The defect of this kind of dynamic impact test equipment is that the initial height of the impact block cannot be increased infinitely, and the speed it can reach when it hits is limited after all. With the continuous improvement of the safety requirements of the body structure, the require...

[0003] The test methods include dynamic impact test and static test. Relatively speaking, the dynamic impact test can more accurately reflect the performance of parts. The existing dynamic impact test equipment for body parts is usually a vertical drop type. Accelerate the free fall of the impact block, so that the impact block hits the body parts at a predetermined speed. The defect of this kind of dynamic impact test equipment is that the initial height of the impact block cannot be increased infinitely, and the speed it can reach when it hits is limited after all.

With the continuous improvement of the safety requirements of the body structure, the requirements for the impact speed of the dynamic impact test are also getting higher and higher, and the existing vertical drop dynamic impact test equipment is obviously unable to meet the requirements of the high-speed dynamic impact test.

In addition, in the existing vertical drop dynamic impact test, it is difficult to lift the large-mass impact block, the efficiency is low and there are potential safety hazards
