基于功能分析系统技术的迷你自行车改进设计

Improved Design of Mini Bike Based on FAST Method

针对迷你自行车部件尺寸影响骑行的问题,运用工业设计及人机工程学知识进行改进:提出了基于FAST法的功能问题,建立功能树选定设计改进点;建立自行车传动模型,计算了传动系统尺寸配置;分析了迷你自行车主要尺寸对骑行的影响,设计了基于骑行动作与车身尺寸的车架伸缩机构;研究迷你自行车安全性涉及的问题,通过分析车架改进后骑行姿态特征,设计了基于人机工程学分析的车座。通过改进设计使迷你自行车满足悠闲骑乘需求。

For mini bike riding affected by the size of components,this paper improved this problem combined with industrial design and ergonomics knowledge.Presented functional problems based on FAST method,selected design elements by setting up FAST functional tree;introduced the bicycle transmission model,calculated the size of transmission system;discussed riding influence caused by size of components,designed bike frame telescopic mechanism based on riding action and frame size dimension adjustment;introduced problems involved in mini-bike safety,studied mini bike riding posture characteristics after improving frame,designed bike saddle based on ergonomics analysiss.By improving the design,mini bike riding meets the leisure needs.
