基于ADAMS的机械柔性疏花机执行机构仿真分析

Simulation of Mechanical Thinning Flower Actuator Based on ADAMS

机械柔性疏花过程中,执行机构是影响疏花效果的关键构件。执行机构主轴转速、所产生扭矩及疏花胶条对目标花朵所产生的击打力大小都是柔性疏花过程中的关键因素。为此,基于ADAMS软件,对执行机构进行动力学仿真分析,以期得到具有科学价值的仿真数据。对机械柔性疏花机执行机构动力学仿真的主要目标是:在给定的主轴转速下,分析主轴所提供的扭矩值及疏花胶条对目标花朵的打击力数值。ADAMS平台的仿真结果显示:在主轴转速为800r/min时,主轴对疏花胶条所提供的扭矩值为6.2N·m,疏花胶条对目标花朵的打击力值为6.4N。考虑到建模和仿真与实际情况之间的误差及接触点选取等因素,仿真结果是正确的。

Thinning actuator plays an important role in the process of mechanical thinning flower .When working the spindle speed , torque , and force values of actuator are the key factors .In this paper dynamics simulation analysis for the actuator of mechanical thinning flower is done based on ADAMS to get the data with scientific value .The main objective of the simulation is to get torque values and force values with fixed spindle speed .Simulation results show that：When the spindle speed is 800rpm /min,the torque is 6.2Nm, and force is 6.4N.Taking into account the error of various parame-ters set in ADAMS , the simulation results are right within the acceptable range .
