The invention discloses a bicycle wind tunnel experiment table device, which is divided into an upper layer and a lower layer, a lower layer structure is provided with a control motor, the control motor converts the rotary motion of the control motor into the up-down motion of a swing frame through a connecting apparatus, and the up-down swing of an uppermost layer table top is realized through the motion transmission effect of the upper layer structure. A bearing is installed between a fixing frame and a wheel of a bicycle fixing apparatus, and internal lead screws and external knobs are arranged in a horizontal guide rail and a vertical guide rail of a wind speed measuring apparatus. According to the invention, simulation of uphill and downhill or wind power borne by each side surface ofthe bicycle can be realized, and rotation motion of bicycle wheels can be maintained so as to better simulate the real state of the bicycle in the advancing process. In addition, the device can be used for various types of bicycle wind tunnel experiment researches, and can also be used for researching the relationship between a certain part of a bicycle and air resistance.
Description
technical field [0001] The invention relates to a bicycle wind tunnel test bench device, in particular to a liftable and rotating wind tunnel test bench, which belongs to the technical field of bicycle test experiments. Background technique [0002] Bicycles are the most common means of transportation in our lives. Especially with the popularity of shared bicycles, bicycles frequently appear in the public's field of vision. However, for bicycles, the air resistance encountered by bicycles during driving is often restricted. It depends on the speed and effort of the rider. In recent years, how to obtain the relationship between bicycle structure and air resistance, and design low air resistance bicycles has attracted widespread attention. The wind tunnel experiment is widely used to study the interaction between the actual object or object model and the gas flow because of its advantages of accurately controlling the experimental conditions and high accuracy of the experimen...
