Problems solved by technology

[0003] At present, there are relatively few test devices for vehicle testing, and the existing vehicle test devices have less freedom, and it is difficult to simulate the state of each wheel of a car in contact with different undulating road surfaces
Moreover, many automotive vibration test devices do not consider environmental factors during vibration tests, resulting in low test accuracy

Embodiment Construction

[0024] Such as figure 1 As shown, an automobile vibration test device is mainly composed of an environmental chamber (1), an installation floor (2), a Stewart parallel mechanism (3), a control system (4) and a hydraulic drive system (not marked).

[0025] Such as figure 1 with figure 2 As shown, the environmental cabin (1) integrates temperature, humidity and light adjustment equipment, which can realize the control of environmental factors such as temperature, humidity, and light radiation in the cabin.

[0026] Such as figure 1 with figure 2 As shown, a cabin door (101) is installed on the side wall on one side of the length direction of the environmental cabin (1) to allow test vehicles and personnel to enter and exit; an observation window is left on the side wall on the side of the width direction of the environmental cabin (102) is used to observe the test status; the four corners of the top of the environmental chamber (1) are equipped with lifting rings (103), which is con...

Abstract

An automobile vibration test device mainly comprises an environmental cabin, an installation floor, Stewart parallel mechanisms, a control system and a hydraulic drive system; the installation floor and the Stewart parallel mechanisms are arranged inside the environmental cabin; four Stewart parallel mechanisms are symmetrically mounted on the installation floor, and an automobile to be tested isplaced on the four Stewart parallel mechanisms; all the tires of the automobile are in contact with moving platforms of the Stewart parallel mechanisms; the control system controls the hydraulic drivesystem to drive the Stewart parallel mechanisms to act to simulate vibration of the automobile during road driving. The automobile vibration test device can simulate a collision relationship betweenthe entire automobile and a road surface, can realistically reflect the vibration state of the automobile with road surface fluctuation, can perform relevant tests including vibration test, noise test, and fatigue endurance test on the entire automobile according to the temperature, the humidity and a lighting condition provided by the environment cabin. The automobile vibration test device can reduce the test time of the automobile and improve the test effect.

Description

[0001] The invention belongs to the field of vehicle testing devices, and particularly relates to a vehicle vibration testing device used for simulating road conditions to test the performance of the entire vehicle. Background technique [0002] With the development of society, modern automobile design pursues lightweight, safety and comfort. When a car is driving on an undulating and pothole road, the working conditions of the car will also change according to the changes in the road conditions. At this time, the various parts of the car show different states. In order to test the performance of the car under different road conditions (such as fatigue durability, shock absorption performance, noise performance, etc.), it is necessary to test the car under different working conditions. Common tests for automobiles are divided into real vehicle road test and laboratory bench simulation test. Among them, the laboratory bench simulation test has the following advantages compared wit...
