后悬挂农具田间试验平台

Field Experiment Platform for Rear Suspension

为了解决现有后悬挂农具测试系统测试项目少和试验平台少的问题,在汲取其他试验平台设计经验的基础上,设计了一种牵引式多挡位后悬挂农具田间试验平台。根据静力学平衡原理,绘制了试验平台液压三点悬挂性能曲线;并在田间拖拉机、田间试验平台、试验平台悬挂2BDM-12型小麦对行播种机、试验平台悬挂2BMSF-12/6型免耕施肥播种机等4种工况下进行了转向操作性、行驶直线性和动力输出轴最高转速等功能试验。4种工况下转向操作性不变,加装试验平台后转向操作性、行驶直线性和最高转速虽有变化但在允许范围之内。试验结果表明该田间试验平台设计满足后悬挂农具田间试验功能要求。

According to the problems of few test projects and test platforms in the existing rear suspension testing system,a tractive rear suspension multi-position rear suspension field experiment platform was designed on the basis of the relative design experience.Based on the statics principles,the suspension performance curves of hydraulic pressure three points were drawn.The steering operational,driving linearity and power output shaft with the highest speed under tractor,experiment platform,experiment suspending 2BDM-12 wheat specific row no-till dill and experiment suspending 2BMSF-12 /6 no-till dill were tested in the field.The results showed that the steering operational,driving linearity and power output shaft with the highest speed had some changes but within allowed limits under four conditions.Therefore field experiment platform met the requirements of the rear suspension equipment tests in the field.
