A kind of aerodynamic test system and test method of automobile frame

Abstract

The invention relates to an automobile frame aerodynamics test system and a test method. The automobile frame aerodynamics test system comprises a test base, a supporting device, a locking device anda fan, wherein a square groove is arranged on a middle portion of the test base; the outer end of the square groove of the test base is symmetrically provided with an arc groove; the front side wall of the square groove on the test base is provided with a controller; the square groove of the test base is internally provided with the supporting device; the top part of the supporting device is provided with the locking device; the fan is mounted at the right top part of the test base; and the supporting device comprises a rotating motor, a rotating supporting plate, a rotating sliding column, aguiding cylinder, a guiding mechanism, a supporting cylinder, a supporting connecting plate and a detecting mechanism. The problems that when the existing frame is subjected to aerodynamics test, different types of frames can not be locked, the frame placing position needs to be adjusted and put straight manually, multi-angle aerodynamics test on the frame can not be carried out, detection of theframe aerodynamics test is inaccurate 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 frame aerodynamic test system and a test method. Background technique [0002] The frame is the support and connection bracket on the car. The frame is generally composed of longitudinal beams and cross beams; the more used frame is the side beam type, and the side beam type frame consists of two longitudinal beams on both sides and several The beam is generally located at the outer end of the longitudinal beam, and the longitudinal beam and the beam are connected by riveting or welding to form a strong rigid frame; the stability of the frame is directly related to the driving safety of the car, so the frame needs to be used before use. To carry out the wind power test on it, the frame must not only carry out the wind power test on its front end, but also carry out the wind power test on the side of the frame, so as to detect the stability o...

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides an automobile frame aerodynamics test system and test method, which can solve the existing problems that different types of frames cannot be locked and the frame cannot be placed when the wind power test is performed on the existing frame. The position needs to be adjusted manually, the wind power test of the frame cannot be performed at multiple angles, and the detection of the wind power test of the frame is not accurate, etc. It can realize the function of multi-angle wind power test for different types of frames Different types of frames can be locked, the position of the frame can be automatically adjusted and straightened, the wind power test can be carried out on the frame from multiple angles, and the wind power test of the frame can be detected accurately, etc.
