多功能共享单车机械结构设计与优化

Design and Optimization of Multi-Functional Shared Bicycle Mechanical Structure

摘要: 由于社会经济的快速发展，共享单车已成为人们出行的必备工具。本文针对传统的共享单车结构单一，停放占用空间较大，且储物空间有限等问题，设计了一种具有可折叠、可变形能力的多功能共享单车结构。首先为保证多功能自行车在变形时仍保持车筐的功能和车身整体平衡，通过对非骑行状态下的自行车把手、车座及辅助装置折叠，设计了一种组合式的自行车车筐结构，并对承载状态下的自行车车架进行设计和强度校核。最后应用ANSYS Workbench对自行车结构进行仿真分析和优化设计，使自行车的结构更加简洁有效，使用性能和寿命大大提高，加快折叠式共享单车的使用和推广，满足更大的社会需求。

Abstract: Due to the rapid development of the social economy, shared bicycle has become an indispensable tool for people to travel. Aiming at the problems of traditional shared bicycle structure, large parking space and limited storage space, this paper designs a multi-functional shared bicycle structure with foldable and deformable capabilities. Firstly, in order to ensure the function of the basket and the overall balance of the vehicle body when the multifunctional bicycle is deformed, a combined bicycle basket structure is designed by folding the bicycle handle, the seat and the aux-iliary device in the non-riding state. The bicycle frame under load is designed and checked for strength. Finally, ANSYS Workbench is used to simulate and optimize the bicycle structure, which makes the bicycle structure more concise and effective, greatly improves the performance and life, accelerates the use and promotion of folding shared bicycle, and meets the needs of larger society.
