一种自行车停放装置的设计

A design of the bicycle parking device

针对自行车停放过程中存在的问题,设计了一款可收拢式自行车停放装置。首先,基于建立的物理模型测量了自行车形态特征值。然后,提出一种由多组连杆机构组成的可收拢式自行车停放装置,并将测量特征值作为该装置功能尺寸计算的输入参数,完成了整个装置结构尺寸设计。最后,建立了停放装置运动仿真模型,并运用ADAMS动力学软件进行了停放效能实验。结果表明:在收拢停放过程中,自行车质心最大角加速度为0.14 r/s^(2),停放装置稳定性较好;该装置在占地面积为2.2 m 2的情况下,可以完成多辆自行车停放。

Aiming at the problems existing in the process of bicycle parking,a retractable bicycle parking device is designed.Firstly,the morphological eigenvalues of bicycle are measured based on the established physical model.Secondly,a retractable bicycle parking device composed of multiple groups of linkage mechanisms is proposed,and the measured eigenvalues are taken as the input parameters for the functional size calculation of the device,and the structural size design of the whole device is completed.Then,the motion simulation model of the parking device is established,and the parking efficiency experiment is carried out by using ADAMS dynamics software.The experimental results show that:in the process of bicycle parking,the maximum angular acceleration at the center of mass is only 0.14 r/s^(2),and the stability of the parking device is good.The device can park multiple bicycles when the floor area is only 2.2 m 2.
