Vehicle body aerodynamic performance test generating system and test method

Abstract

The invention relates to a vehicle body aerodynamic performance test generating system and a test method. The system comprises a test board, a test device and a blowing device, wherein a square slot is arranged on a middle portion of the test board; the test device is installed in the square slot arranged in the test board; the blowing device is arranged on the top of the right end of the test board; the test device comprises a gravity scale, a detection bottom board, a support board, a blocking frame, a screw motor, a screw, an inner strut, a flap mechanism, a test mechanism, a guiding body and a screw connection board; the blowing device comprises an arc support board, a curved moving block, a wind cylinder, a moving motor, a moving rotation shaft, a rotating gear and a rotation shaft connection board. The problems the existing vehicle aerodynamic test can not perform accurate positioning for different vehicles, the wind power detection result is inaccurate, a wind direction cannot be adjusted, a detection value can not be intuitively displayed and the like can be solved.

Description

technical field [0001] The invention relates to the technical field of automobile performance detection, in particular to an automobile body aerodynamic performance test generation system and a test method. Background technique [0002] The wind power test of the vehicle is to test the performance of the vehicle when the wind resistance is large. The wind power is that the air flow around the car will have various effects on the vehicle when the car is running. The air can produce resistance to the car and consume energy. Especially when the car is running, the airflow collides with the vehicle and separates, a part of the airflow will float over the top of the car, and a part of the airflow will float over the bottom of the car. The law "the faster the fluid velocity, the lower the pressure", so the air pressure on the top of the car is smaller than that on the bottom, resulting in an upward air lift, which seriously affects the driving safety of the vehicle; but on the oth...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides an automobile body aerodynamic performance test generation system and test method, which can solve the problem that existing vehicles cannot be accurately positioned and wind power detection for different vehicles when performing wind power tests. The results are inaccurate, the wind direction cannot be adjusted, and the detection value cannot be displayed intuitively. It can realize the wind power test of different vehicles and display the detection results. It has the ability to accurately locate and wind power for different vehicles. The detection results are accurate, the wind direction can be adjusted, and the detection values ​​can be displayed intuitively, etc.
