摘要

粘煤的不断积累使煤仓仓壁表面粗糙不平,进而造成原煤在煤仓中的流动受到阻碍,针对这一问题,设计了一种中心回转式全液压清仓机,并对其执行机构进行了分析计算与仿真研究。仿真结果表明:整机结构的等效应力最大值约为74 MPa,整体变形量最大值约为3.603 3 mm,优化后,等效应力最大值下降至66 MPa,整体变形量最大值下降至1.787 9 mm。设计的清仓机的强度符合设计要求,工作油缸的活塞杆优化后满足工况要求。
        The accumulation of viscous coal makes the surface of coal bunker rough and uneven,which hinders the flow of raw coal in the bunker. Aiming at this problem,a central rotary full hydraulic cleaning maching was designed,and its executive mechanism was analyzed,calculated and simulated.The simulation results show that the maximum equivalent stress is about 74 MPa and the maximum overall deformation is about 3.603 3 mm. After optimization, the maximum equivalent stress is reduced to 66 MPa and the maximum overall deformation is reduced to 1.787 9 mm. The strength of the designed cleaning machine meets the design requirements,and the piston rod of the working cylinder meets the working conditions after optimization.
