尾鳍推进式水上自行车设计

Design of tail fin water bicycle

介绍一种基于鲹科鱼类推进机理的水上自行车,主要结构由减速齿轮传动机构、曲柄滑块摇杆机构、方向指示针、支撑体和尾鳍组成。通过对相关机构运动学分析并运用ADAMS对其进行运动仿真,得出该设计机构能够满足设计要求。以上机构能使鱼尾摆动和暂停实现前进和转弯,机动性较好且省力效果显著。

Based on propulsion mechanism of fish,a kind of water bicycle is introduced in this paper.The main components include reduction gear transmission mechanism,slider-crank and rocker mechanism,direction indicator and support and tail fin.Through the kinematic analysis of relevant mechanism and simulating the motion by ADAMS,the design institution can satisfy the design requirement.The mechanisms above can make the bicycle forward and turn by controlling the tail suspension and swinging.Good flexibility and saving effect is remarkable.
