【摘要】：港口集装箱起重机滑轮压痕失效是目前困扰工业界的难题之一。由于滑轮与钢丝绳的接触过程十分复杂,滑轮压痕磨损过程受多种因素的影响,导致滑轮压痕磨损机理的研究至今没有取得突破性进展。本文以振华重工(简称ZPMC)生产的SECT-61T-8113型岸边集装箱起重机主起升系统为研究对象,通过采用解析法与ADAMS仿真及有限元分析相结合的研究方法,对滑轮与钢丝绳之间的接触应力及滑轮压痕磨损进行了深入分析。主要研究工作和研究结果包括：通过对岸桥主起升滑轮与钢丝绳的运动规律进行了分析,结合实际的结构参数和实际作业过程的运行参数,得到滑轮在搬运和回程中的位移、速度和加速度随时间的变化曲线及滑轮1和滑轮2两侧的钢丝绳随时间的受力变化曲线；通过对主起升滑轮与钢丝绳接触的力学分析,建立了能够对钢丝绳和滑轮接触应力进行计算的方法和解析计算模型,得到滑轮绳槽表面的应力分布情况和最大接触应力,并根据线性疲劳累积损伤理论计算出初装滑轮和淬火层被磨损后的发生疲劳点蚀的时间；根据疲劳磨损理论及钢丝绳对滑轮的切削机理,分析滑轮产生压痕的原因；采用ADAMS仿真分析软件建立简化后的主起升系统虚拟样机模型,分析集装箱在装吊过程各运行阶段的钢丝绳受力值,发现其与解析法计算结果有较好的一致性；采用ANSYS有限元分析软件分析钢丝绳侧股看成圆柱及考虑侧股外层钢丝时,滑轮绳槽表面承受最大压力下的接触应力分布,发现其与解析法计算结果具有较好的一致性。本文的研究结果可为SECT-61T-8113型岸桥有关滑轮压痕问题的解决提供借鉴。
[Abstract]:The indentation failure of port container crane pulley is one of the most difficult problems in industry. Because the contact process between pulley and wire rope is very complicated and the wear process of pulley indentation is affected by many factors, no breakthrough has been made in the study of wear mechanism of pulley indentation. In this paper, the main hoisting system of SECT-61T-8113 quayside container crane produced by Zhenhua heavy Industry (ZPMC) is taken as the research object. The analytical method is combined with ADAMS simulation and finite element analysis. The contact stress between pulley and wire rope and indentation wear of pulley are analyzed. The main research work and results are as follows: through the analysis of the motion law of the main lifting pulley and wire rope of the shore bridge, the displacement of the pulley in the transportation and return range is obtained by combining the actual structural parameters and the operating parameters of the actual operation process. The variation curve of velocity and acceleration with time and the stress curve of wire rope on both sides of pulley 1 and pulley 2 are analyzed by means of mechanical analysis of the contact between main lifting pulley and wire rope. The method and analytical calculation model for calculating contact stress of wire rope and pulley are established, and the stress distribution and maximum contact stress on the surface of pulley rope groove are obtained. According to the theory of linear fatigue cumulative damage, the time of fatigue pitting after the wear of the primary pulley and quenched layer is calculated, and the causes of the indentation of the pulley are analyzed according to the theory of fatigue wear and the cutting mechanism of the pulley by wire rope. The simplified virtual prototype model of the main hoisting system is established by using ADAMS software, and the stress value of the wire rope during the loading and lifting process of the container is analyzed. It is found that the model is in good agreement with the analytical method. ANSYS finite element analysis software is used to analyze the contact stress distribution on the surface of pulley rope groove under the maximum pressure when the side strand of wire rope is regarded as a cylinder and a steel wire with the outer layer of the side strand is considered. It is found that the contact stress distribution is in good agreement with the analytical calculation results. The results of this paper can be used for reference to solve the problem of pulley indentation on SECT-61T-8113 shore bridge.
