摘要: 为降低破篼刀具的工作能耗及解决破篼刀具工作半径不可调的问题,设计一种工作半径可调以实现从竹篼内部破篼的刀具。首先在ANSYS中建立竹篼—破篼刀具有限元模型,然后进行破节、破壁仿真并做试验分析,最后构建试验平台加以验证。结果表明:所研制的破篼刀具可清理外径为110~130mm的竹篼;破节最优的刀具参数组合为:轴向刀后角角度为30°、刀盘转速为5000r/min;破壁的刀具参数组合为:径向刀后角角度为20°、刀盘转速为5000r/min。

Abstract:  In order to reduce the energy consumption of bamboo stump cutter and solve the problem  that the working radius of cutter cannot be adjusted, a cutter with an adjustable working radius is designed, which can break bamboo stump from inside the stump. First of all, a finite element model of bamboo stumpbamboo stump cutter is established in ANSYS, then jointbroken and wallbroken simulation is carried out and test analysis is done, finally, a test platform is built to verify it. The results show that the bamboo stump cutter developed in this paper can explode bamboo stump with an external diameter of 110-130 mm. The optimal parameter combination of jointbroken is as follows, the back angle of axial cutter is 30°, and the speed of cutter is 5 000 r/min. The parameter combination of wallbroken is that the back angle of radial cutter is 20°, and the cutter speed is 5 000 r/min.
