Embodiment Construction
[0027] The following with attached Figure 3 to Figure 6 A trolley device for reproducing the side collision of automobiles according to the present invention will be further described in detail.
[0028] A trolley device for reproducing the side collision of automobiles according to the present invention, please refer to Figure 3 to Figure 6 Relevant figures include a barrier system 1, a buffer system 2 and a trolley system 3. The trolley system 3 includes a side wall 31, and the left end of the side wall 31 is releasably offset against the right end of the barrier system 1. The left end of the buffer system 2 is fixedly connected to the right end of the barrier system 1 , and the right end of the buffer system 2 is releasably offset against the left end of the trolley system 3 . Like this, trolley system 3 comprises side wall 31, and the left end of side wall 31 is connected with the right end of barrier system 1, also can disconnect; As long as the left end of the buffer...

The invention discloses a bogie device for reproducing side collision of an automobile. The device includes a wall barrier system, a buffer system and a bogie system. The bogie system includes a sidewall; the left end of the side wall releasably abuts against the right end of the wall barrier system; the left end of the buffer system is fixedly connected to the right end of the wall barrier system; and the right end of the buffer system releasably abuts against the left end of the bogie system. The bogie device for reproducing the side collision of the automobile has characteristics of beingsimple in structure, being easy to manufacture, being low in cost, being able to stimulate a displacement curve of collision and intrusion of a real vehicle, and the like, can replace an existing early-stage structural verification collision test of a finished vehicle, and solves problems of high testing expenses of the finished vehicle, high cost of a sample vehicle, complicated equipment, and the like; and compared with testing methods such as the finished vehicle, the device has higher process reliability.
Description
technical field [0001] The invention relates to the technical field of automobile safety tests, in particular to a trolley device for reproducing automobile side collisions. Background technique [0002] At present, the side impact pedestal test is mainly a dual-speed platform side impact pedestal test method, that is, the speed curve of the door inner panel is converted into a double-platform characteristic curve through analysis and fitting, and the curve is applied to the vehicle test device. The trolley test devices using this theory mainly include: Seattle Safety side impact trolley device and IST side impact trolley device, the schematic diagram is as follows figure 1 with figure 2 shown. [0003] Seattle Safety side impact trolley device includes cylinder 01, door trolley 02, servo trolley 03, energy absorbing parts 04, servo brake device 05, air brake device 06 and seat trolley 07. The acceleration curve of the car door is generated by the resultant force of the ...
