Impact testing machine of pneumatic piston type automobile parts

Abstract

The invention discloses an impact testing machine of pneumatic piston type automobile parts which comprises a running track used for sliding a model car, wherein one end of the running track is provided with an impact screen; the model car can move by the aid of a traction guide mechanism; the traction guide mechanism comprises an air cylinder which drives a piston to move through an air supply port, and the piston is connected with a guide rope which winds on two pulleys; the model car is provided with an automatic clamping and release device and a buffer device; the automatic clamping and release device are connected with the guide rope; the automatic clamping and release device comprises a cam mechanism; and the high point and the low point of the cam mechanism are connected with a clamp. The invention has the advantages of convenient and quick testing, accurate speed control and short accelerating travel, can test the parts instead of real automobile so as to greatly lower the testing cost.

Description

technical field [0001] The invention relates to an automobile model crash test device, in particular to a simulated crash test machine for testing auto parts. Background technique [0002] In the collision test between a car and a structure, it is necessary to accelerate the car to a set speed and make it collide with the structure. Because the car crash test has a certain degree of risk and unpredictability, generally the driver does not drive the car, but accelerates the test car by external force. At present, the methods for accelerating the test vehicle mainly include electric traction, hydraulic drive, tractor traction and so on. Among them, electric traction is the most widely used method, and its main advantage is high control accuracy. [0003] However, in terms of the prior art, even the crash test of individual auto parts needs to pass the whole vehicle test, which is not only inefficient, but also greatly wastes cost, which is not conducive to multiple tests to ...

AI Technical Summary

Problems solved by technology

[0003] However, as far as the prior art is concerned, even the crash test of individual auto parts needs to pass the whole vehicle test, which is not only inefficient, but also greatly wastes cost, which is not conducive to multiple tests to obtain accurate results

In particular, some manufacturers of auto parts do not need and do not have the conditions for real vehicle testing, so it is very difficult to conduct product testing

At present, the domestic auto parts crash test is still a blank
