Abstract

The invention relates to the technical field of bicycle body supporting frames, in particular to a bicycle wind tunnel test bed device which comprises a frame, two sinking type guide rail sets, a transmission part and friction parts, wherein the two sinking type guide rail sets are installed on the frame in a distance variable mode, and the gravity center of each sinking type guide rail set is lower than that of the frame; supporting parts for supporting a front wheel and a rear wheel of the bicycle are respectively mounted on the two sinking type guide rail sets; the two friction parts are rotatably mounted on the two sinking type guide rail sets and are in transmission connection through the transmission part, and after one friction part is in sliding friction with the rotating rear wheel of the bicycle, the other friction part and the front wheel of the bicycle are driven to operate through the transmission part. The sinking type guide rail set is combined with the supporting part to stably support the bicycle for wind tunnel test, wind resistance can be effectively reduced, performance stability is kept, the test result is reliable, the overall structure is simple, and the sinking type guide rail set with the variable distance is suitable for various types of tested bicycles.

Description

technical field [0001] The invention relates to the technical field of vehicle body support frames, in particular to a bicycle wind tunnel test bench device. Background technique [0002] For a bicycle, a large part of the resistance comes from the air. Especially in road races, the low wind resistance of bicycles can directly determine the final competition results, and the optimization of bicycle drag reduction has received extensive attention. Real data can be obtained through wind tunnel tests on bicycles, which can provide reference for computer fluid simulation results, better optimize the structure of road bicycles, and reduce wind resistance. [0003] However, most of the wind tunnels are currently built for the automotive and aviation fields. The number of wind tunnels specially designed for bicycles is very small, and the test cost is too high; Meet the existing bicycle wind tunnel test requirements. Contents of the invention [0004] The object of the present...
