液力飞轮及其在快速自行车上的应用研究
|
摘要
经济的快速发展和城市化进程的持续推进使城市交通越来越拥挤,虽然很多大城市都在公共交通的建设上投入巨资,改善人们的出行条件,如修建地铁、开通快速通道、增加巴士数量。但是,随着人们生活水平的日益提高和时间观念的逐渐增强,对出行的便捷性、快速化的要求越来越高。为了适应大众工作生活对出行的需求,需要一种快速化、轻量化、环境友好的交通工具,从而减少路途时间和疲劳,健康身心提高工作效率,降低出行成本,避免拥挤,改善公共交通环境。因此,研制一种使用液力飞轮启动的快速自行车,作为人们出行工具具有非常重要的意义。
论文主要对小轮自行车的典型结构进行了简单分析,在此基础上,对小轮自行车的行进系统和结构进行改进,增加液力飞轮驱动系统,为骑行建立初速度,实现车辆人力骑行的快速化,对改进后的液力飞轮启动系统组成元件进行设计计算,深入解析了液力飞轮液力作用的过程,并对快速自行车的液力飞轮系统及其组成元件、液力飞轮加速车辆过程、骑行蹬踏加速过程等建立数学模型,利用MATLAB软件对液力飞轮系统进行了仿真研究,仿真结果表明,快速自行车的液力飞轮系统有效地完成自行车的快速化。
对小轮自行车的快速化设计和研究,提高了现有自行车的速度,拓宽了自行车的使用范围,为人们摆脱单一依靠汽车的中短途旅行提供了一种新思路,也为其它非燃油车辆的研究和开发提供参考。对快速自行车的液力飞轮系统的研究、理论推导及仿真研究,为液力传动理论在民用交通工具中的实际应用进行了有益的探索。
With the rapid improvement of city and fast development of economy, the urban traffic for citizen is becoming more and more crowded. The government has invested much in order to better the communication condition, such as building subway and separating the express and adding more busses. These benefit people but can not satisfy those who want to drive quickly and conveniently anywhere while life level has made great progress and time becomes more and more costful. To fill the demand of new driving people,a kind of new appliance with high speed and hand-taking should be set up to reduce time and comfort driver so as to enhance the working efficiency after driving. This new set will not cost too much but run easily when traffic jams. The research will reform the urban traffic greatly. So. the study of how to build a new kind of fast-riding bike.which is equipped with hydraulic inertia-wheel, and make it popular has great significance.
This paper mainly analyzes the structure of the classic-type bicycle with little wheel. Based on this analysis, the betterment on marching systm and structure of little wheel bike, new model has been designed against the rapid driving system and its parts. Also, mathematical model of the system and parts is established and the MATLAB software is used to carry out simulation. The simulation results indicates that the inertia wheel system drive the bike running rapidly.
By the design and theoretical study on the little wheel bicycle and the fast riding system, the speed of bike is elevated. This extended utilization for the bike and provide people a new solution for short-middle travel. It also established a reference for designing and researching non-oil car. The deducing process for basic theory and simulation research of inertia wheel system provides beneficial exploration for the design of hydraulic machine.
