58/2023年第12期岸边集装箱起重机侧向载荷下的轮压计算方法孙亚平林伟华王克海曾鹏上海振华重工(集团)股份有限公司上海200125摘要:文中在对比FEA有限元轮压和传统算法轮压的基础上,分析了两者的相同点和不同点,指出侧向载荷下的扭转是导致两者差异的原因。以结构门框横梁为切入点,分析了结构内力对轮压的作用,将门框扭转分解为左右侧、海陆侧力偶和集中力矩,将总轮压分解为倾覆力矩轮压与扭转轮压之和,提出了轮压传递系数的概念,从而得到了一种扭转轮压算法模型。另外,结合FEA获得门框不同受力条件下的轮压传递系数,经验证该算法模型与FEA结果符合较好。关键词:岸边集装箱起重机;轮压;载荷;扭转;刚度;模型中图分类号:U653.921文献标识码:B文章编号:1001-0785(2023)12-0058-06Abstract:Inthispaper,onthebasisofcomparingFEAfiniteelementwheelpressurecalculationwithtraditionalwheelpressurealgorithm,thesimilaritiesanddifferencesbetweenthemarediscussed,anditispointedoutthattorsionunderlateralloadisthereasonforthedifferencebetweenthetwocalculationmethods.Takingthebeamofstructuraldoorframeasthestartingpoint,theinfluenceofstructuralinternalforceonwheelpressurewasanalyzed.Thetorsionofdoorframewasdecomposedintoleftandrightside,seaandlandsidecoupleandconcentratedmoment,andthetotalwheelpressurewasdecomposedintotheoverturningmomentwheelpressureandtorsionalwheelpressure.Thewheelpressuretransfercoefficientwasputforward,andanalgorithmmodeloftorsionalwheelpressurewasbuilt.Inaddition,combinedwithFEA,thewheelpressuretransfercoefficientofdoorframeunderdifferentstressconditionswasobtained,anditisverifiedthatthealgorithmmodelisingoodagreementwithFEA.Keywords:quaysidecontainercrane;wheelpressure;load;twist;stiffness;model0引言岸边集装箱起重机(以下简称岸桥)是广泛应用于码头前沿、船和码头之间的集装箱装卸设备。岸桥的轮压情况影响着总体布置,是总体计算中的首要内容。在码头建成后,许用轮压是确定的,随着岸桥设备参数的大型化,部分码头轮压逐渐达到传统设计极限。传统轮压算法与有限元分析(FiniterElementAnalysis,FEA)直接计算轮压相比,在受侧向载荷时具有显著差异,在主梁放平时的传统轮压结果偏大。因此,优化传统轮压计算方法成为降低计算轮...
