Vehicle dynamic rolling test equipment and method thereof

Abstract

The invention discloses vehicle dynamic rolling test equipment and a method thereof. The equipment comprises a rolling test device, the rolling test device comprises a test surface, the test surface is one or more of a sediment surface, an upper slope surface and a lower slope surface, and the test surface is used for providing different rolling speeds and rolling angles for a to-be-tested vehicle, so that the lateral acceleration of the to-be-tested vehicle reaches a critical acceleration; wherein the critical acceleration is the lateral acceleration applied to the rollover of the to-be-tested vehicle and calculated according to the vehicle rollover model. After a traction system accelerates the to-be-tested vehicle to a preset test speed, the to-be-tested vehicle passes through the testsurface, so that the data acquisition device acquires working condition test data of the to-be-tested vehicle in the driving and rolling processes in real time, and the working condition test data isused for calibrating vehicle design. Through different working condition simulations, related working condition test data can be accumulated and used for the calibration of vehicle design, the safetyperformance development capacity of the whole vehicle is improved, and hidden dangers existing in personnel after an automobile rollover accident are reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle entertainment, in particular to a vehicle dynamic rollover testing device and a method thereof. Background technique [0002] The airbag is a very important part of the passive safety system of the automobile, and its reliability is an extremely critical index in the design process of the airbag. All can bring great injury to the occupant if leak point detonation takes place, delay detonation, misdetonation detonation. The current draft of mandatory standards and regulations "Methods and Requirements for Malfunction Test of Automobile Airbag System" mainly includes three types of testing methods: static test, roadblock test and rough road test. The tests for automobile side airbags are mainly basketball impact test, bicycle simulation impact test and side road shoulder impact test, all of which impact the side of the vehicle with a collision object to check the safety of side airbag malfunction. ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a vehicle dynamic rollover test equipment and method thereof, which can solve the problem that the current airbag ECU verification test cannot realize the functional verification of the vehicle under dynamic rollover conditions, and is designed according to the existing vehicle design and calibration standards. Vehicles, there is still a big hidden danger to the personnel after the car rollover accident
