摘要 Berman法是一种用实验模态参数对初始有限元动力模型进行修正的方法,目前在工程中应用较为广泛,本文针对该方法的不足之处,提出了一种改进Berman修正法,并研制了修正软件GMOD,通过理论算例和工程实际算例验证了改进的修正方法和相应软件的正确性和实用性。 Berman medification methd(BMM)which is used widely in engineering is a kind of improvedmethed for Finite element models using experimental medel analysis.In this paper, an improvedBerman modification method(IBMM)is raised,and a relevant software GMOD is developed.Aftertesting to several examples, IBMM and the program GMOD proved correct and practical.
