移栽机支承部件受力分析及有限元仿真

Force Analysis and Finite Element Simulation on Supporting Part of Transplanting Machine

移栽机可解决人工种植费工、费时的问题。本文对移栽机支承部件的主梁和轮边减速器箱体进行了力学模型简化和受力分析,并通过有限元软件进行仿真,得到了主梁和轮边减速器箱体的应力云图和位移云图,得出了主梁和轮边减速器箱体应力和变形水平在安全范围之内的情况,并提出了改进建议:首先,在满足强度条件下适当增加主梁的壁厚以减轻整机质量,使机器运行更加灵活;其次,在轮边减速器箱体内添加筋板增加其强度,提高整机的安全性能,为设计和生产出性能更加优越的移栽机提供参考。

Transplanting machine solved the state of a lot of work-consuming and time-consuming through artificial planting. The simplified mechanics model and the force analysis on supporting part consist of the main girder and the wheel reducer boxes of transplanting machine were completed. The stress nephogram and the displacement nephogram of the main girder and the wheel reducer box were achieved through the finite element simulation. The conclusion that the stress and de- formation level of the main girder and the wheel reducer box are within safe range was received, and the improvement pro- posals were presented. Firstly, under the safe strength condition, the wall thickness of the main girder may be appropriately increased to lighten the weight of machine, which causes the machine movement to be more flexibility. Secondly, the rein- forcement plate could be increased in the wheel reducer boxes to enhance its strength, which improves the security of the machine. These proposals provided reference for designing and producing the transplanting machines with better perform- ance.
