Experimental studies on the vibration of perforated sheet-中国Betway体育网页登陆

摘要 Intheexperimentwehavemeasuredtheresonantfrequenciesofper-foratedsheetswithperforationratesfrom0.008to0.30.Comparedthosefre-quencieswiththecorrespondingresonantfrequenciesofhomogeneous,orun-perforatedoneweobtainedanempiricalrelationshipbetweentheresonantfrequencyandperforationrate,whichcanbeusedforindustrialpurpose.Wehavealsostudiedthechangeofvibrationalenergydistributionofperforatedsheetrelatedtothatofhomogeneous.
