油茶果振动采摘系统运动特性分析

摘要

针对曲柄连杆式油茶果振动采摘机的结构和工作状态，建立了1个两自由度的采摘机-果树振动系统动力学模型，推导了该模型的振动微分方程，并用拉普拉斯变换进行了求解。对振动系统进行了数值计算，分析了不同夹持高度对采摘机和果树振动的影响。%In the light of the structure and working conditions of slider crank vibratory camellia oleifera harvester , a dy-namic model of two degrees of freedom of harvester-fruit tree vibration system was established .The vibration differential equation of the model was derived , and Laplace transform was applied to solve it .Numerical simulation of the vibration system and the analysis of the effect of clamping height on the vibration of harvester and fruit tree were carried out .
