摘要
采用电液伺服材料试验机的位移加载方式,对金属橡胶/橡胶复合叠层耗能器进行动态特性研究,在此基础上结合理论分析建立了耗能器的动力学模型,并利用傅里叶级数展开技巧辨识出模型中的未知参数,对比理论与试验结果表明,所建模型可靠且参数识别精度能够满足工程应用的要求。
Making use of the precise displacement controlling of the material testing machine,the dynamic characteristics of metal rubber/rubber composite laminated energy dissipater has been studied.Based on experimental and theoretical studies,the dynamic modeling of energy dissipater is established and the Fourier series expansion is used to identify the parameters of modeling.By contrasting of testing results and theoretical results,it is shown that the dynamic modeling is reliable and identification accuracy is able to satisfy the require-ments of engineering application.
