Collision type trolley test device

Abstract

The invention discloses a collision type trolley test device, which mainly includes a collision trolley, a gantry frame, an elastic rope, a pulley, a slide rail, and a traction device. The collision trolley is arranged at both ends of the slide rail. The pulleys are arranged on the bottom plate, and the colliding trolley is provided with a trolley wheel system, a decoupling device, an energy-absorbing tube fixing device, and a locking device. The collision trolley slides along the direction of the slide rail through the trolley wheel system and pitches along the direction vertical to the slide rail, and the collision trolley is separated from the elastic rope through the decoupling device before the collision occurs. The invention has a reasonable structure and meets the needs of the colliding trolley collision test, and different test devices can be installed on the trolley bracket according to different test purposes, and the pitching during the collision process of the trolley can be simulated while realizing the collision Movement, meanwhile, the device is less restricted by the site, and the manufacturing cost is low.

Description

technical field [0001] The invention belongs to the field of automobile collision testing, in particular to a collision type trolley test device. Background technique [0002] With the rapid development of the automobile industry, automobile safety is more and more concerned by consumers. Improving automobile collision safety can not only improve the overall performance of automobiles, but also an important measure to effectively reduce the casualty rate of traffic accidents. Some countries with developed automobiles such as Europe and the United States have started research on automobile collisions since the beginning of the 20th century. As early as 1999, the Ministry of Machinery Industry of my country promulgated the certification regulations for frontal collision occupant protection vehicles (CMVDR294). Now the international automobile safety regulations and my country's relevant regulations have strict regulations on automobile collision detection. In order to meet th...

Problems solved by technology

At the same time, the higher the collision speed, the longer the required runway, which is easily restricted by the test site

In addition, the current trolley wheels basically use fixed wheel trains, so that the trolley can only move along the direction of the slide rail, so that the trolley loses its pitching motion during the collision process, which is different from the actual car collision form
