摘　　要：针对金属橡胶迟滞回线的非对称特性,提出了非对称度判定因子λ,并结合钢丝绳非对称迟滞模型和金属橡胶迹法模型,建立了一种用于描述其非线性动力学特性的数学模型。试验结果表明,该模型较好地反映了金属橡胶构件迟滞回线的非对称特性,可满足工程分析金属橡胶非线性动态特性的需要。According to the asymmetric characteristics of metal rubber hysteresis loop,the judgment factorλof asymmetry degree is proposed.Combined with the asymmetric hysteresis model of steel wire rope and metal rubber trace method model,a mathematical model for describing its nonlinear dynamic characteristics is established.The test results show that the model better reflects the asymmetric characteristics of hysteresis loop of metal rubber components,and can meet the needs of engineering analysis of nonlinear dynamic characteristics of metal rubber.
