| 摘要: |
| 【目的】对旋耕机的运动过程进行仿真分析，获得与系统匹配的旋耕机运动参数。【方法】利用MATLAB分析了旋耕机切土节距、功率消耗与机组前进速度、刀轴转速、耕幅等的关系，并分析旋耕刀的运动轨迹及端点速度。【结果】根据旋耕机对切土节距以及功率消耗的要求，设计旋耕机的较优运行组合参数为：前进速度vm=0.72 m/s，刀轴转速n=240 r/min，耕幅B=0.8 m。根据设定的参数，由旋耕刀端点的运动轨迹可知其耕深为0.2 m，沟底凸起高度为0.02 m。在设计参数下，旋耕刀端点速度的大小和方向呈周期性变化，证明运动参数的选取是合理的。【结论】在旋耕机的运动分析过程中使用MATLAB技术，易于得到与系统匹配的运动参数。 |

| Abstract: |
| 【Objective】This paper obtained matching parameters of rotary tiller by simulation of its movement.【Method】MATLAB was used to analyze the relationship among advance speed,rev rotate speed and cutting pitch and power consumption of the rotary cultivator.The trajectory and speed of rotary blade were also analyzed.【Result】According to the requirements of rotary cultivator to cutting pitch and power consumption,the designed operational parameters of rotary tiller were:vm=0.72 m/s,n=240 r/min,and B=0.8 m.The size of depth was 0.2 m and the height of sole was 0.02 m from the movement locus of rotary blade picture with operational parameters.Speed of rotary tillage cutter endpoint velocities from operational parameter verified that the selection of motion parameters were reasonable.【Conclusion】It was easy to get matching parameters using MATLAB in motion analysis of rotary cultivator. |
