摘要
针对9P-150型单螺杆秸秆膨化机膨化螺杆因磨损严重而导致的寿命较短问题,研究螺杆在磨料属性确定条件下的受力分析及磨损机理,通过分析秸秆磨料与螺杆摩擦与磨损的行为机理,建立螺杆磨损的数学模型。利用Edem软件对螺杆受力及磨损情况进行模拟,模拟结果与实际情况一致。所得结论将为研究螺杆受力及磨损状况的优化打下理论基础。
In view of the short life of the straw extruder with 9P-150 single screw due to serious wear,the mechanical analysis and wear mechanism of the straw extruder under the condition of determining abrasive properties were studied.EDEM software was used to simulate the stress and wear of the screw.The conclusions obtained in this paper will lay a theoretical foundation for the optimization of screw stress and wear condition.
