利用三维设计软件Solid Works对小型自走履带式灌木割灌机进行结构设计,建立三维模型,将建立好的切削机构三维模型导入ADAMS中,在ADAMS环境下搭建切削机构虚拟样机模型,在此基础上对切削机构在工作过程中关键点的位移、速度、加速度以及所受力进行分析,建立刀具切削运动的数学模型。通过仿真结果可以清楚直观地了解到小型自走履带式灌木割灌机的切削机构各组成部分在进行作业时的运动特性曲线。在ADAMS仿真软件分析的基础上,在ANSYS有限元分析软件中对重要零部件进行强度分析。为设计人员对割灌机切削机构的设计和改进提供一定的参考。
The structural design of small self-propelled crawler shrubber cutter is carried out by using Solid Works software, and the three-dimensional model is established. The established three-dimensional model of cutting mechanism is imported into ADAMS. The virtual prototyping model of cutting mechanism is built under ADAMS environment. Based on this, On the cutting mechanism in the work of the key points of displacement, velocity, acceleration and force analysis, the establishment of a mathematical model of cutting tool movement. Through the simulation results can clearly and intuitively understand the small self-propelled shrubber brush cutter cutting mechanism when the components of the movement characteristics of the curve. Based on the analysis of ADAMS simulation software, the strength analysis of important components in ANSYS finite element analysis software is carried out. Provide some reference for designers to design and improve the cutting mechanism of brush cutter.
