Design and analysis of handbarrow for climbing obstacles

针对崎岖地况上的运输问题,设计出一种行星轮越障运货车,由蓄电池、电机、行星轮、车厢、减速器、传动轴、调平机构等部件组成,选取爬楼工况对行星轮进行越障能力计算,通过计算结果确定电机选型,由电机输出功率计算出传动轴、减速器等主要零部件尺寸,整车后方安装调平机构实现转向和调节重心,在结构设计完成后,借助SolidWorks对整体结构进行三维建模,用有限元分析软件ANSYS Workbench对主要零部件进行线性结构分析,结果表明车厢、传动轴符合强度和刚度要求。

Aiming at the transport problems on the rugged ground, a kind of handbarrow for climbing obstacles has been devised,which consists of battery,motor, planetary gear, compartments reducer, drive shafts, leveling mechanism and other components. The obstacle capacity is calculated according to the case of climbing stairs. The moto is selected by rated load, and the size of the drive shaft, the gear unit and other major components are calculated by the output power of the motor. The leveling mechanism is installed in the rear of the vehicle to achieve the steering and adjust the focus. After the design is complete,SolidWorks is used to create a three-dimensional model and make linear structural analysis for main components with finite element analysis software called ANSYS Workbench. The results show that compartment and drive shaft can meet the requirment of the strength and stiffness.
