基于模糊滑模控制的液压自适应支座控制策略研究液压气动与密封/2024年第2期doi:10.3969/j.issn.1008-0813.2024.02.005摘要:重载列车通过波浪干扰下的高架浮桥时,桥梁在竖向和横向会产生振动,列车存在偏载时,还会导致桥梁两侧产生位移差。针对以上问题,建立液压系统非线性模型,结合模糊滑模控制、交叉耦合同步控制和三状态反馈控制方法,通过液压自适应支座对波浪干扰和桥梁振动进行主动控制。利用ADAMS和MATLAB/Simulink进行联合仿真,结果表明:液压自适应支座能有效控制桥梁振动和两侧位移同步误差,对波浪升降能实时补偿,提高了列车通行时的安全性。关键词:高架浮桥;液压自适应支座;模糊滑模控制;交叉耦合同步控制中图分类号:TH137.51ZHANGLian-peng',ZHANGLong-long",QIUWei-min',FENGJiel,CAOPeng",LIJun-jing'(1.ShijiazhuangTiedaoUniversitySchoolofMechanicalEngineering,Shijiazhuang050000,China;2.TianjinQixingLichuangTechnologyCo.,Ltd.,Tianjin301700,China)Abstract:Whenaheavy-haultrainpassesthroughanelevatedpontoonbridgeunderwaveinterference,thebridgewillvibrateverticallyandlaterally,andwhenthetrainhasaneccentricload,itwillalsocauseadisplacementdifferenceonbothsidesofthebridge.Inviewoftheaboveproblems,anonlinearmodelofhydraulicsystemisestablished,andthewaveinterferenceandbridgevibrationareactivelycontrolledbycombiningfuzzyslidingmodecontrol,cross-couplingsynchronouscontrolandthree-statefeedbackcontrolmethodbycombiningfuzzyslidingmodecontrol,cross-couplingsynchronouscontrolandthree-statefeedbackcontrolmethod.UsingADAMSandMATLAB/Simulinkforjointsimulation,theresultsshowthatthehydraulicadaptivebearingcaneffectivelycontrolthevibrationofthebridgeandthesynchronouserrorofdisplacementonbothsides,andcompensateforthewaveliftingandloweringinrealtime,whichimprovesthesafetyofthetrainwhenpassing.Keywords:elevatedpontoonbridge;hydraulicadaptivebearing;fuzzyslidingmodecontrol;cross-coupledsynchronouscontrol争时后勤保障和平时的应急抢修的工作提供方便。本0引言研究在国内外研究的基础上,以八七型抢修钢梁为研当铁路桥梁受到破坏时,恢复施工难度大,传统的究对象,分析桥梁振动响应问题,并研究液压自适应支浮桥和抢修钢梁通过橡胶支座连接,...
