Introduction Stackercraneshavebecomeawidelyusedtechnologyforthestorageandretrievalofgoodsinmodernhigh-baywarehouses.Thesetypesofsystemsarecharacterizedbytheirabilitytotransportgoodsfromonelocationtoanotherquickly,efficiently,andwithminimalhumanintervention.However,stackercranesalsopresentcertainchallengesrelatedtotheirdesignandoperation. Oneofthemostcriticalaspectsofstackercranedesignisthedynamicresponseofthestructure.Inparticular,thedynamicresponseoftheaislestackercranestructurecanbeaffectedbyavarietyoffactors,includingthemovingmassoftheload,thespeedofoperation,andthevibrationfrequencyofthestructureitself.Thesefactorscanleadtounwantedvibrationandnoisethatcannegativelyaffecttheoverallperformanceofthesystem.
