摘　　要：根据螺旋翼碎土刀盘的工作特点,分析、建立了与刀盘结构参数相关的刀盘转矩、功耗及生产率数学模型,对刀盘的主要结构参数,即阿基米德螺线转角、阿基米德螺旋面转角和刀盘顶角对刀盘转矩及生产率的影响进行计算机仿真分析;以计算机仿真分析结果为基础,以最小功耗和最大生产率为目标函数,对螺旋翼刀盘的阿基米德螺线转角、阿基米德螺旋面转角和刀盘顶角等3项主要结构技术参数进行了优化分析。数值仿真及优化结果可用于螺旋翼刀盘的设计及应用。According to the work characteristics of spiral soil crushing disk cutter, structuralparameters-related mathematical models of the cutter torque, power consumption and productivity are established. Influences of main structural parameters of the disk cutter, Archimedes spiral angle, Archimedes helical angle and top angle of the disk cutter, on cutter torque and productivity are comput-er-simulated and analyzed. On the basis of computersimulationresults, the three main structural parameters of the cutter are analyzed and optimized taking minimized power consumption and maximized productivity as target functions. Results from numerical simulation and optimization can be applied to the design and application of helical disk cutters.
