摘要
对高分子粘弹性阻尼器减振机理进行了分析研究，将分数导数模型引入静态特性公式，得出了矩形截面粘弹性阻尼器动态刚度与阻尼的表达式，并利用ＢＥＡＭ法对阻尼器进行了实验测试，实验结果与计算值较相吻合，因此可通过元件的静态特性公式直接计算出矩形截面粘弹性阻尼器的动态特性参数。
The properties of viscoelastic dampers of high polymer is investigated and theexpression for the rigidity and damping of elastomer damper with rectangular cross-section isobtained by combining fractional derivative calculus model with static properties predictingformulae.A proof test is given.and the agreement of the result of the analysis with that ofmeasurement is fair. Thus the dynamic properties of the damper with rectangular cross-sec-tion can be determined by using the static properties predicting formulae.
