Trolley for simulating side collision test of car

Abstract

The invention discloses a trolley for simulating a side collision test of a car. The trolley comprises a chassis, wherein a rear end frame is welded at the rear end of the chassis, car wheel modules are installed at four vertex corners of the chassis, a linear bearing module is installed at the front end of the chassis, four groups of collision rods are installed on the linear bearing module, thefront ends of the four groups of collision rods are provided with a first buffer device, a car door installation tool are installed on the three upper groups of collision rods, a seat installation pedestal is installed on the bottommost collision rod, a car roof frame is installed above the rear end frame and the linear bearing module, the linear bearing module is provided with a gas curtain installation bracket, a side buffer is installed at the front end of the linear bearing module, and the front end of the side buffer is provided with a second buffer device. The trolley improves the simulation effect of the side collision test of the car, can accurately simulate the impact conditions of different parts of a dummy during the side collision, and reduces the test cost.

Description

technical field [0001] The invention relates to a trolley for simulating a car side impact test, belonging to the field of passive safety of automobiles. Background technique [0002] Cars are one of the most important means of transportation in modern times, and the safety problems brought about by them have been paid more and more attention by people. Compared with the frontal collision of a car, the occupant is closer to the door, so the side collision of the car will cause greater damage to the occupant. At present, one kind of car door collision test is to study the safety performance of the car in the side collision process by impacting the car door with external equipment and detecting the deformation of the car door. This type of side impact test can detect the specific deformation of the door after a side impact, but the accuracy of the detection data for the impact of the occupant during the side impact of the vehicle is relatively poor. Another type of car door ...

AI Technical Summary

Problems solved by technology

Although this scheme can measure the impact of the dummy, it is not a collision simulation using the impact force. Therefore, it is quite different from the side impact in the actual situation, and the accuracy of the obtained data is not high.

The current side impact test equipment can only simulate a single working condition in side impact, and will cause damage to the door, the door cannot be reused, and the test cost is high
