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。
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 .
