【摘要】：港口集裝箱起重機(jī)滑輪壓痕失效是目前困擾工業(yè)界的難題之一。由于滑輪與鋼絲繩的接觸過程十分復(fù)雜,滑輪壓痕磨損過程受多種因素的影響,導(dǎo)致滑輪壓痕磨損機(jī)理的研究至今沒有取得突破性進(jìn)展。 本文以振華重工(簡稱ZPMC)生產(chǎn)的SECT-61T-8113型岸邊集裝箱起重機(jī)主起升系統(tǒng)為研究對象,通過采用解析法與ADAMS仿真及有限元分析相結(jié)合的研究方法,對滑輪與鋼絲繩之間的接觸應(yīng)力及滑輪壓痕磨損進(jìn)行了深入分析。主要研究工作和研究結(jié)果包括：通過對岸橋主起升滑輪與鋼絲繩的運(yùn)動(dòng)規(guī)律進(jìn)行了分析,結(jié)合實(shí)際的結(jié)構(gòu)參數(shù)和實(shí)際作業(yè)過程的運(yùn)行參數(shù),得到滑輪在搬運(yùn)和回程中的位移、速度和加速度隨時(shí)間的變化曲線及滑輪1和滑輪2兩側(cè)的鋼絲繩隨時(shí)間的受力變化曲線；通過對主起升滑輪與鋼絲繩接觸的力學(xué)分析,建立了能夠?qū)︿摻z繩和滑輪接觸應(yīng)力進(jìn)行計(jì)算的方法和解析計(jì)算模型,得到滑輪繩槽表面的應(yīng)力分布情況和最大接觸應(yīng)力,并根據(jù)線性疲勞累積損傷理論計(jì)算出初裝滑輪和淬火層被磨損后的發(fā)生疲勞點(diǎn)蝕的時(shí)間；根據(jù)疲勞磨損理論及鋼絲繩對滑輪的切削機(jī)理,分析滑輪產(chǎn)生壓痕的原因；采用ADAMS仿真分析軟件建立簡化后的主起升系統(tǒng)虛擬樣機(jī)模型,分析集裝箱在裝吊過程各運(yùn)行階段的鋼絲繩受力值,發(fā)現(xiàn)其與解析法計(jì)算結(jié)果有較好的一致性；采用ANSYS有限元分析軟件分析鋼絲繩側(cè)股看成圓柱及考慮側(cè)股外層鋼絲時(shí),滑輪繩槽表面承受最大壓力下的接觸應(yīng)力分布,發(fā)現(xiàn)其與解析法計(jì)算結(jié)果具有較好的一致性。 本文的研究結(jié)果可為SECT-61T-8113型岸橋有關(guān)滑輪壓痕問題的解決提供借鑒。
[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.
