摘  要：
通过Solid Works设计了圆盘式生草刈割机的虚拟样机,然后利用机械系统动力学自动分析(Automatic dynamic analysis of mechanical systems,ADAMS)虚拟样机分析软件对其工作过程进行仿真,得到刀片旋转一周时的运动轨迹,对模型进行三因素三水平多指标的正交试验,并对试验数据采取综合平衡法,确定切割器运动参数的最佳取值,结果表明,前进速度为2.74km·h~(-1),刀盘速度为2 000r·min-1,刀片数为3片时,重割区与漏割区面积有效减少。利用实体样机在田间试验,测试了切割器的运动参数与性能指标,结果显示,仿真数据真实可靠,对于圆盘式果园生草刈割机运动参数选择具有指导意义。

摘  要：
The virtual prototype of a disc grass cutting machine was designed by Solid Works,and its working process was simulated by ADAMS(Automatic dynamic analysis of mechanical systems)to obtain the blade rotation trajectory.The orthogonal experiment had three factors and three levels and a multi-index model was obtained.To determine the best value of the movement parameters,the comprehensive balance method was adopted.When the forward speed was 2.74 km·h~(-1),the rotation speed was 2000 r·min-1,the number of the blade pieces was 3,and the area of repeat cut and missed cut were effectively reduced.The motion parameters and performance index of the solid prototype were tested in the field,and the results showed that the simulation data were reliable and significant for selection of motion parameters of the disc orchard grass cutting machine.
