摘要
履带拖拉机在丘陵山地行驶的稳定性对拖拉机的工作效率以及驾驶人员的安全性有很大影响。本文采用Solidworks建立履带拖拉机与旋耕机具三维模型,在Recurdyn仿真软件的Track(LM)模块中建立行走装置,在Ground模块建立路面模型,针对旋耕机挂接角度对履带拖拉机的稳定性进行仿真分析。采用仿真与试验相结合的方法,旨在通过质心垂向速度以及俯仰角变化趋势来评估农具悬挂角度对履带拖拉机的稳定性影响。研究结果表明:在挂接机具角度为11°时的旋耕机组在坡道行驶的稳定性大于空载履带拖拉机的稳定性,不同挂接机具角度的履带拖拉机在砂壤土、黏土、干沙土、硬质4种典型路面上爬坡行驶时,硬质路面最稳定,砂壤土与黏土相对稳定,干沙土最不稳定,当挂接机具角度为11°、23°、35°的履带拖拉机在砂壤土上爬坡时,机具挂接角度为11°、35°时行驶稳定性相对较好,机具挂接角度为23°时稳定性最差。
The stability of crawler tractors running in hills and mountains has a great influence on the working efficiency of tractors and the safety of drivers.This article uses Solidworks to build a three-dimensional model of a crawler tractor and a rotary tiller,a walking device in the Track(LM)module of Recurdyn simulation software,and a road model in the Ground module.The stability of the crawler tractor is based on the angle of attachment of the rotary tiller Simulation analysis.This paper adopts the method of combining simulation and experiment,and the research aims to evaluate the influence of the hanging angle of the farm implement on the stability of the crawler tractor through the vertical speed of the center of mass and the change trend of the pitch angle.The research results show that the stability of the rotary tiller driving on the slope when the angle of the attachment tool is 11°is greater than the stability of the unloaded crawler tractor.The hard road is the most stable when climbing on four typical roads,the sandy loam and clay are relatively stable,and the dry sand is the most unstable.When the crawler tractor with the attachment angle of 11°,23°,and 35°is on the sandy loam When climbing,the driving stability is relatively good when the attachment angle is 11°and 35°,and the stability is the worst when the attachment angle is 23°.
