Abstract

An automobile collision simulation trolley device comprises a trolley and a track. The trolley comprises a linear sliding table sliding along the track linearly and a deviation platform for fixing a testing trolley body. A hinged structure is arranged between the linear sliding table and the deviation platform. The hinged structure is arranged in the middle of the deviation platform, and a deviation power source for pushing the deviation platform to rotate is arranged between two ends of the sliding table or two ends of the deviation platform. The automobile collision simulation trolley device relates to an automobile passive safety test detecting device, solves the problem that testing data obtained by the existing simulation trolley test can not reflect a dynamic process related to vehicle body deviation motion during collision of an automobile, and provides a good testing searching device for designing and manufacturing the automobile with good safety performance.

Description

technical field [0001] The invention relates to an automobile passive safety test detection device, in particular to an automobile collision simulation trolley. Background technique [0002] At present, there are two main types of vehicle crash safety performance tests: real vehicle crash test and crash simulation test. The test cost of the crash simulation platform is low, and it is a commonly used test and detection device in the process of automobile design and development. [0003] The Chinese patent document published on 2005-06-08, the publication number is CN2703686, and the title is "automobile front trolley collision test device" discloses a kind of automobile front trolley collision test device: the braking waveform controller rear end fixed plate is fixed On the ground, the beams on both sides are fixedly connected to the steel cylinder, and two reinforcing ribs are fixedly connected to each side of the steel cylinder, and the inner cavity of the steel cylinder i...
