基于 Pro/E 的水稻秧盘摆放机的设计与模拟仿真分析

摘要

Using ProE software design a placement machine for seedling-growing bowl tray , through the transmission de-vice of transverse feed mechanism and execute device of vertical feed mechanism to achive rice Yangpan implementation work .According to mechanics calculate the horizontal instantaneous angle α=30 °-35 °when seedling tray contact with ground .Using motion simulation module of ProE software to conducted the dynamic simulation for propulsion system , ob-tained under four different velocity of Yangpan trajectory , through analyzing the kinematic trajectory can draw a line chart of Seedling tray vertical velocity and tanαchange over time in different levels of speed , optimize the use of αrange opti-mum range actuators advance speed of 100-150 mm/s.%运用Pro／E软件设计了一种针对水稻植质钵育秧盘的摆放机，通过传送装置的横向进给机构与执行装置的纵向推进机构实现水稻秧盘的摆放工作，并根据力学原理推算出秧盘和地面接触时秧盘与水平面瞬间夹角α＝30°～35°。应用Pro／E软件中运动仿真模块对推进装置进行了动态仿真，得到了在4种不同水平推进速度下秧盘运动轨迹，通过对机构的运动轨迹分析绘制出不同水平速度时秧盘竖直速度和 tanα随时间变化折线图，并利用α范围优化出执行装置推进速度的最佳范围为100～150 mm／s。
