一种新型AGV驱动单元结构设计与分析

Structural Design and Analysis of a New Type of AGV Drive Unit

在深入研究AGV工作原理的基础上,针对AGV小车在搬运质量较大货物时,出现驱动轮打滑或摆动的现象,从AGV驱动机构设计方面进行分析,进一步研究AGV小车。该文以六轮差速驱动机构为依托,构建了一种独立悬挂的新型驱动单元结构,通过两种驱动单元连接结构的分析对比和基于ANSYS的分析验证了该机构的可行性和强度可靠性。基于上述设计的样机进行试验,结果表明该驱动单元结构能够上下窜动保证驱动轮与地面的完全接触,进而有效的解决驱动轮打滑和车体摆动问题,使AGV能够适应全地形工作。

On the basis of in-depth research on the operational principle of AGV,for AGV car when transporting greater quality goods,there is a driving wheel slip or swing phenomenon,It is analyzed from the AGV drive mechanism design,further study of AGV. Based on the six wheel differential drive mechanism,a new type of independent suspension drive unit is constructed,By analyzing the comparison of the two drive units based on ANSYS analysis,it verify the feasibility and reliability of the mechanism. Test based on the design of the prototype,the results show thatthe structure of the drive unit can ensure the full contact between the driving wheel and the ground,thuseffectively solve the problem of wheel slip and the body swing,so AGV can adapt to all-terrain work.
