Abstract

The invention provides a collision test device and relates to a test device. The collision test device aims at solving the problems that an existing collision test device is complex in structure, capable of conducting emission only through matching between a balancing body and a collision body, low in gunpowder utilization rate and serious in pollution to a test field. According to the collision test device, a working table is horizontally arranged and fixedly connected to a foundation; a first base, a second base and a third base are sequentially and fixedly connected to the working table; a first braking unit is mounted on the first base; a second braking unit is mounted on the second base; a counter-recoil unit is mounted on the third base; a transmitting tube body penetrates through the first braking unit, a first transmitting tube through hole, the second braking unit, a second transmitting tube through hole, the counter-recoil unit and a third transmitting tube through hole in sequence, and the transmitting tube body, the first transmitting tube through hole, the second transmitting tube through hole and the third transmitting tube through hole are arranged in a spaced mode. The collision test device is scientific and reasonable in structural design and low in manufacturing cost and is applied to high-speed large-mass collision physical tests, and the transmitting track of the collision body is accurate.

Description

technical field [0001] The invention relates to a test device, in particular to a crash test device. Background technique [0002] In existing physical collision tests, the colliders used are generally large-diameter and high-mass objects, generally with a diameter between 200 mm and 1000 mm, or higher. Existing test devices all adopt the principle of balanced acceleration, and the collision body and the balance body are loaded in the middle of the launch tube at the same time, and the left and right sides are symmetrical. The mass of the collision body and the balance body are equal, and the gunpowder is arranged between the collision body and the balance body. When launching, the gunpowder gas simultaneously pushes the two to accelerate, and the force is balanced, and the frame basically has no force movement. The kinetic energy of the backward movement of the balancing body is equal to the kinetic energy of the forward movement of the colliding body. The use of such a ...
