摘  要:
花生清选分离是花生收获机作业过程中最重要的项目之一,是收获机的核心部件,其性能的好坏直接关系到收获机的作业质量,其主要的指标是含杂率与损失破碎率。为了提高花生清选分离装置的设计效率、缩短设计周期,提出了一种基于ADAMS的花生收获机清选装置虚拟设计和仿真方法,并对核心部件做了重点设计,包括轮轴和星型轮。利用非自由质点坐标系和广义坐标系,结合拉格朗日方程的位置和速度约束,建立了清选装置的机械系统运动学微分方程。使用ADAMS软件对不同转速条件下的轮轴工作效果进行了动力学仿真,得到了3种不同速度下的Y轴速度曲线,通过比较曲线的震动效果,选择合适的轮轴转速,对花生收获机的优化设计具有重要的借鉴意义。

摘  要:
As the most important one of the items,peanut cleaning and separation is peanut harvester operation process that the core part of the harvester,whose performance is directly related to the work quality of the harvester. And its main target is the impurity rate and loss of broken rate. In order to improve peanut cleaning device for separating the design efficiency and shorten the design cycle,it presents a peanut harvester based on ADAMS cleaning apparatus virtual design and simulation methods,and focus on the design of key parts,including wheel and the star wheel. By using the non free particle coordinate system and the generalized coordinate system,the differential equation of the mechanical system of the cleaning device is established based on the position and velocity constraints of Lagrange equation. By using ADAMS software under the condition of different speed of shaft work effect were dynamics simulation,it describes three different speeds of Y axis velocity curve. By comparing the curve of the vibration effect,it selected the appropriate shaft speed.And the peanut harvesting machine optimal design has important significance.
