摘　　要：针对电力特种装备———新型自驱动式牵引机的关键装置双摩擦牵引卷筒设计缺乏设计依据等关键问题,采用微积分及有限元仿真分析结合的方法进行了力学分析,得到牵引钢丝绳沿双摩擦卷筒绳槽的张力变化函数关系,进而建立了卷筒的力学分析模型,研究在不同载荷条件作用下卷筒的应力状态与关系。最后,基于ANSYS软件对卷筒进行有限元建模分析,并将仿真结果与理论计算结果进行分析比较。结果证明了所采用的单元梁力学模型应用于卷筒的应力计算的可靠性与有效性,可为摩擦卷筒类零件的强度设计提供重要的理论依据,具有一定的工程意义。In consideration of key problems as the design of dual-friction drums on the new type self-driven towing machine,which is special power equipment,has been lack of necessary design basis,and mechanical analysis has been carried out by the method of combining the calculus with finite element simulation.Functional relation of tension changes in the wire rope along the drums grooves was obtained,and mechanical analysis model of drum was presented.The stress state of the drums and their relationship under different load conditions was studied.The finite element model of drums was established and analyzed by applying ANSYS software.The simulation result was compared with that of theoretical calculation.It shows that applying the unit beam mechanical model in stress calculation of drums was proven to be suitable and effective,and has great significance and engineering value for the strength design of friction tube-type parts.
