跟据振动减阻机理,对4UD -600型马铃薯挖掘机振动机构进行改进设计。在 ADAMS 软件中建立了4UD -600型马铃薯挖掘机振动机构的参数化模型,通过分析物料在分离筛筛面上的相对运动,在保证较高筛选效率的前提下,以生产率最高为优化目标对机构进行了优化设计,得到了机构最优参数组合:曲柄 LOA =5.5 mm ,摆臂LBD =570 mm ,主筛摆连杆 LEF =110 mm ,连杆 LJK =160 mm ,曲柄转速 nOA =4666°?s -1。优化后物料沿筛面的平均移动速度从0.089 m?s -1提高到0.122 m?s -1 ,挖掘机生产率显著提高,理论的正确性在后续的实际改进设计中已得到验证。

According to the mechanism of turbulent drag reduction ,improved the design of 4UD - 600 potato dig-ger .A parametric model for the vibrating structure of 4UD - 600 potato digger was established using ADAMS software . After analyzing the relative motions of materials on separating screen surfaces ,to achieve highest productivity ,an opti-mization of this vibrating structure was performed ,and resulted in optimal combination of parameters .The optimal combi-nation of parameters were :the length of crank LOA = 5 .5 mm ,the length of swing arm LBD = 570 mm ,the length of main screen pendulum rod LEF = 110 mm ,the length of connecting rod LJK = 160 mm ,the speed of crank nOA = 4 .666°?s - 1 . After this optimization ,results showed that the average moving speed of materials along the screen surfaces was increased from 0 .089 m?s - 1 to 0 .122 m?s - 1 ,significantly improving the productivity of the excavator .Validity of the theory had further been verified in subsequently actual improvement design .
