Simulation test device for automobile side collision

Abstract

The invention provides an automobile side surface collision simulation testing device, belonging to the technical field of automobile collision simulation; the device can re-show the real mechanic environment of the side collision of the automobile, can be used for the detection and design improvement of driving safety products and driven safety products such as automobile doors, safety belt, safety lock, safety seat, safety airbag, automobile interior and the like, and can provide a mean for human biomechanics research under collision environment; the automobile side surface collision simulation testing device forms an automobile collision simulation system by a hydraulic automobile door energy absorber, a trolley energy absorber and a brake energy absorber which are arranged on a simulation movable obstacle vehicle; and the trolley is provided with a vehicle door motion control mechanism and a seat motion control mechanism. The automobile side surface collision simulation testing device has the beneficial effects that the automobile side surface collision simulation testing device can clearly reflect the motion relationship of the automobile door, the seat and the automobile door during the side surface collision of the automobile, can simulate the working environment of the driving and driven safety products during the side surface collision process of the automobile and has the advantages of high simulation precision, simple design procedure, compact structure of the device, small volume, easy operation and the like.

Description

technical field [0001] The invention belongs to the technical field of automobile collision simulation, and in particular relates to an automobile side collision simulation test device. It can be used for performance testing and design improvement tests of active and passive safety products such as car doors, seat belts, safety locks, safety seats, airbags, and car interiors. a means of testing. Background technique [0002] Improving the safety of automobiles and effectively reducing the losses caused by automobile road traffic accidents is one of the important tasks of my country's automobile industry in recent years. Compared with frontal collisions, side collisions cause more damage to occupants. The statistics of traffic accidents in recent years show that about 40% of accidents are side collisions, and about 30% of fatal and serious injuries are caused by side collisions. -40%. Therefore, in the early 1980s, developed countries in the West carried out side impact te...
