新型货物多用途运输机构设计与分析

Design and Analysis of a New Multi-purpose Transportation Mechanism for Goods

为解决目前物流运输中存在的货物积压、堆放杂乱、野蛮抛掷、录入信息依靠大量人工等问题,设计了一种集货物信息自动录入、运输、卸载功能的机电气一体化的新型多用途运输机构。该机构主要由PWM电机控制模块、减速器、可旋转式运输装置、自动卸货模块4个部分组成。对机构最薄弱环节(驱动轴)进行可靠性与安全系数法设计的计算分析,结果表明:可靠性设计的轴类零件更为节省材料。利用UG及ANSYS对机构关键零部件进行三维建模和静力学分析,从而优化零部件的结构。最后实体制作样机并进行相关试验,进一步验证多用途运输机构的合理性和实用性。

In order to solve the problems in logistics transportation, such as cargo backlog, piled up messily, savage throwing and input information requiring a lot of manpower, a new multi-purpose transportation mechanism was designed, which integrate with the function of automatically inputting information, transporting and unloading cargo. The mechanism mainly consists of PWM motor control module, the reducer, the rotary transportation device and the automatic unloading module. For the drive shaft,namely the mechanism of the weakest link, the reliability and safety coefficient design method was used to compute and analyze.The results show that reliability design method can save more material for shaft parts. Three dimensional modeling and static analysis were carried out on the key components of the mechanism by using UG and ANSYS software to optimize the structure of the components. Finally, the real prototype was manufactured and tested, which can further verify the rationality and practicality of the multi-purpose transport mechanism.
