Abstract

The invention discloses a one-to-two automobile model wheel rotation wind tunnel test platform. The one-to-two automobile model wheel rotation wind tunnel test platform comprises a rack, a wheel installation shaft, an installation flat plate, a driving motor, a conveying belt and two mobile belt systems, wherein the wheel installation shaft is rotatably supported on the rack, the installation flatplate is supported above the rack, a sliding groove is formed in a surface of the installation flat plate, the driving motor is detachably arranged on the installation flat plate, can move along thesliding groove and further gets close to or deviates from the wheel installation shaft, the two mobile belt systems are respectively arranged at two sides of the installation flat plate and can be used for supporting and driving model wheels to rotate, and the model wheels sleeve two ends of the wheel installation shaft and can rotate around the wheel installation shaft. The driving motor providedby the invention can move along the sliding groove and further gets close to or deviates from the wheel installation shaft, so that the driving motor is used for test of automobile models with different shaft distances. A one-to-two automobile model wheel rotation wind tunnel test method is also disclosed.

Description

technical field [0001] The invention relates to the technical field of automobile wind tunnel tests, and more specifically, the invention relates to a one-to-two automobile model wheel rotating wind tunnel test platform and a one-to-two automobile model wheel rotating wind tunnel test platform control method. Background technique [0002] At present, the world is vigorously advocating the development of a low-carbon economy, and reducing drag and emissions in the automotive field is undoubtedly an important part of a low-carbon economy. With the rapid development of the domestic automobile industry, the study of automobile aerodynamics has been paid more and more attention in the research and development of complete vehicles. Studies have shown that the aerodynamic resistance formed by the wheels and wheel covers accounts for 30% of the total aerodynamic resistance of the vehicle. Therefore, the aerodynamic research of the wheels and wheel covers has become a hot spot, and t...
