小型履带拖拉机行走系统设计分析与实验研究
|
摘要
基于目前乔灌木采收设备生产效率低、设备少的现状,设计了一种小型乔灌木采伐橡胶履带式拖拉机。为此,介绍了拖拉机行走系统的设计,主要部件有驱动轮、履带及支重轮,并针对关键部件驱动轮进行力学分析。通过理论计算和ANSYS力学分析,结果表明:驱动轮的变形量小于屈服强度,变形量在可接受范围内,可以满足驱动轮对履带拖拉机行走系统的使用要求。最后,进行了整机试验,分别在不同路面情况对拖拉机实际行走速度与理论行走速度进行了比较,并得出结论。
Based on the current situation of the low production efficiency and equipment of the shrub and shrub harvesting equipment,a small arbor shrub cutting rubber crawler tractor was designed.This paper only describes the design of the tractor walking system,the main components are driven wheel,track,support heavy wheel,and the key components of the mechanical analysis of the driving wheel.Through theoretical calculation and ANSYS mechanical analysis results show that the deformation of the driving wheel is less than the yield strength,deformation in the acceptable range,can meet the requirements of walking tractor driving wheel system use.At the end of the experiment,the walking speed and the walking speed of the tractor are compared in different situations,and the conclusion is drawn.
