Abstract

The invention relates to the technical field of vehicle body support frames, in particular to a bicycle wind tunnel test bench device. , the center of gravity of the sunken guide rail group is lower than the center of gravity of the frame; the two sets of the sunken guide rail group are respectively installed with supports for supporting the front wheel and rear wheel of the bicycle; The friction pieces are respectively rotatably mounted on the two sets of the sunken guide rail groups, and are connected by the transmission piece. After one of the friction pieces slides and rubs with the rotating rear wheel of the bicycle, the other friction piece is driven by the transmission piece. and the front wheel of the bicycle; the sunken guide rail set in this embodiment is combined with the support to stably support the bicycle for the wind tunnel test, which can effectively reduce wind resistance, maintain stable performance, and reliable test results. Its overall structure is simple, and the spacing is variable The sunken rail set is suitable for a variety of test bike categories.

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 the bicycle can directly determine the final competition result, and the optimization of drag reduction of the bicycle has received extensive attention. Through the wind tunnel test of the bicycle, the real data can be obtained, which can provide a reference for the computer fluid simulation results to better optimize the structure of the road bicycle and reduce the wind resistance. [0003] However, most 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; Meets existing cycling wind tunnel testing requirements. SUMMARY OF THE INVENTION [0004]...
