Description
Technical Field
The invention relates to a trolley for a side collision test of a simulated car, belonging to the field of passive safety of automobiles.
Background
The car is one of the most important transportation means in modern times, and the safety problem brought by the car is more and more emphasized by people. Compared with the front collision of a car, the passenger is close to the door, so the side collision of the car can cause more damage to the passenger. At present, one type of door impact test of an automobile is to impact a door through external equipment and detect the deformation condition of the door to research the safety performance of the automobile in a side impact process. Such a side impact test can detect the specific deformation of the door after a side impact, but the accuracy of the detection data of the impact condition received by the passenger during the side impact of the automobile is poor. Another type of door impact test for automobiles is to detect the impact experienced by an occupant during a side impact. For example, chinese patent publication No. CN202631223U, published as 12/26/2012, entitled side impact test device for automobiles, applies for a side impact test device for automobiles, which includes a base, a rail disposed on the base, a slide carriage disposed on the rail, the slide carriage being capable of sliding along a guide rail, and a limit disposed on the base, and a door support disposed at one end of the guide rail on the base. The vehicle door is impacted by utilizing the inertia of the seat and the dummy, and then the impact condition of the dummy, the displacement condition of the seat and the deformation of the vehicle door are obtained. According to the scheme, when the trolley moves, the dummy and the seat collide against the car door under the action of inertia, and then the collision condition of the dummy is measured. Although the scheme can measure the impact condition of the dummy, the impact simulation is not realized by using the impact force, so that the difference from the side impact condition in the actual condition is larger, and the accuracy of the obtained data is not high. The current side collision test tool can only carry out simulation test on single working condition in the side collision, and can damage the car door, the car door can not be reused, and the test cost is high.
