摘要

使用多学科联合仿真的方式对荸荠(Heleocharis dulcis(Burm. f.) Trin.)收获机泥果分离过程进行了虚拟动力学试验。设计泥果分离装置的虚拟样机,然后建立其刚柔耦合动力学模型并进行动力学仿真,获得振动装置的运动规律。同时,创建荸荠-泥土的颗粒系统模型,并进行离散元仿真。改变弹簧钢板的厚度和宽度进行多次仿真,结果表明,在一定的范围内,钢板的厚度越大,其分离效果越显著,而钢板的宽度对分离效果没有明显的影响。
        Virtual dynamic experiment was carried out on mud-fruit separation of water chestnut harvester by muti-disciplinary collaborative simulation. Firstly,virtual prototype of mud-fruit separation equipment was set up, and then dynamic simulation was carried out on its' rigid-flexible coupled dynamic model to get motion law of vibration equipment. Subsequently particle system model of water chestnut-mud was created and discrete element simulation was carried out on it. Several simulation experiments were carried out by changing the thickness and wideness of spring steel plate. The result showed that separation effect was better with the increasing thickness of the spring steel plate in certain extent, but the wideness of it had less impact.
