摘  要:
设计了一台智能化果树喷雾车,在工作过程中喷药臂靠工作台支撑架来支撑,而工作台的动态特性决定着产品的寿命和质量。为此,在三维建模的基础上,利用ANSYS有限元分析软件,建立了工作台支撑架有限元模型,计算了前10阶模态振型和固有频率等参数,通过对比实验模态分析参数,总结了其结构的高阶振型动态特性,并提出了对结构的修改方案。

摘  要:
The author designed a intelligential spray car of fruit tree,this support frame of worktable support the whole spraying arm in the course,it,s dynamic properties is important to determine the product quality and life.On the basis of three-dimensional modeling,The modal of dynamic that support frame was analysis and the first ten modal parameters(natural frequencies and mode shapes) was calculated by using ANSYS finite element of analysis software.Compared with Modal parameters by method and experimental modal analysis obtained,summarizes the higher modes of dynamic structure,and proposed modifications for the structure.
