Real automobile platform rollover test method based on 23-degree angle

Abstract

The invention provides a real automobile platform rollover test method based on a 23-degree angle. The method comprises the following steps that the automobile quality is adjusted; mark points of an automobile are measured; a passenger compartment is adjusted; a dummy is placed; the automobile is placed and dispatched; state of the automobile after the test is inspected by combining a video; dummydata are downloaded and processed; after the test, mark points of an A column, an upper edge beam, a C column and an automobile roof of the automobile are measured, and the deformation amount is calculated; the test result is analyzed. According to the real automobile platform rollover test method based on the 23-degree angle, the rollover test method of the automobile is built according to actual road traffic conditions in China, and the method is used for effectively testing and evaluating the safety performance of rollover of the automobile.

Description

technical field [0001] The invention belongs to the field of automobile safety testing, and in particular relates to a rolling testing method of a real vehicle platform based on an angle of 23 degrees. Background technique [0002] Real vehicle crash test is the most effective method to comprehensively evaluate vehicle safety performance. Crash test testing is the evaluation of the results of a vehicle body frame being subjected to a crash in a hypothetical accident environment. [0003] According to statistics, in my country's traffic accidents, frontal collision accidents, side collision accidents, rollover accidents, and rear-end collision accidents are relatively common accident forms, which also cause high fatality rates for occupants in vehicles and involve huge property losses. Among these accidents, rollover accidents have the characteristics of low occurrence rate and high mortality rate. Due to the late start of my country's automobile industry, the road traffic ...

AI Technical Summary

Problems solved by technology

In the field of car safety research, due to the complexity of car rollover accidents and the lack of relevant laws and regulations, there is currently a lack of test and evaluation methods for car rollover safety in my country.

[0004] Rollover is the accident form with the highest mortality rate in traffic accidents. The main reasons for the high mortality rate are: on the one hand, the structural strength of the vehicle body is relatively weak, and the vehicle body deforms severely during the rollover process, which reduces the living space of the occupants in the vehicle; On the other hand, the restraint system of the vehicle did not fully function and failed to better protect the occupants in the vehicle
