为促进油茶果产业的健康发展,提高油茶果采摘效率,降低成本,该文设计了一款悬挂振动式油茶果采摘机。在分析采摘执行机构的机构组成和工作原理的基础上,建立了采摘执行机构-油茶果采收动力学模型,得出了该系统稳态响应下的振幅表达式以及影响因素。通过对油茶树实地尺寸测量,对油茶树进行三维建模,利用ANSYS对油茶树建立柔性体模型,运用ANSYS和ADAMS对采摘执行机构-油茶树采摘系统进行刚柔耦合仿真分析,得到侧枝加速度与夹持高度和频率之间的关系以及果树夹持位置的运动轨迹,分析表明,果树在受到双偏心块式激励时,侧枝加速度呈周期性变化,夹持位置做往复直线运动,和采收动力学模型分析一致。利用...

A suspended vibratory actuator for removing camellia fruits from a plant was designed to improve the picking efficiency while reduce the cost. This present picking actuator mainly comprised a vibratory head device for clamping a fruit plant, and a column mechanism for controlling the vibratory head. The column mechanism can make the rotation and lifting of the vibratory head, and consequently the vibratory head can hold the fruit tree while generate an exciting force. A double eccentric structure was used for the excitation mechanism, and a hyd...
