摘要

针对现有自行车健康性与舒适性不能两全的状况,提出了一种鞍座高度可调的方法来改善其短暂停靠的不便。其原理是在传统的自行车结构的车鞍座下部增设刚性可锁定气弹簧,通过安装在车把附近的闸线快速控制气弹簧的伸缩,从而实现车鞍座升降。确定气弹簧设计参数后,对气弹簧的动作过程进行数学建模,得到活塞运动速度、行程及受力三者之间的关系。在将人体重力设定为活塞受力后,利用Matlab仿真出行程z及活塞运动速度v的随时间t的变化规律,车座可在5 s内降到最低位置,达到了快速降高的要求。

Abstract

This paper presents a bicycle saddle height adjustable system,which makes saddle lifted fast. The new system is based on the traditional structure of the bicycle,locates a rigid lockable gas spring under the saddle. Through the gas spring mathematical model,with MATLAB software,obtained the relationship between speed and reaction time,and the displacement curve. Analyzed these variable relationship had made a conclusion that gas spring does it well in lifting the saddle.
