| 摘 要： | 将电流变弹性体材料等效为粘弹性阻尼材料,运用夹层梁理论和广义Hamilton原理,建立了电流变弹性体夹层结构梁的动力学模型,并对其动力学特性进行仿真分析.仿真结果表明,随着外加电场强度的增加,电流变弹性体夹层结构梁的刚度和模态损耗因子得到提高,系统的振动也会减小;增加电流变弹性体夹层的厚度,能降低系统的固有频率,但同时...

| Abstract: | Considered electrorheological(ER) elastomers as the visco-elasticity material,a dynamic model of a sandwich beam filled with ER elastomers is developed based on Hamilton's principle and sandwich beam's theory.Then its dynamic characteristics are analyzed and simulated.Results show that natural frequencies of the ER elastomers sandwich beam increase and vibration amplitudes of the beam decrease as the intensity of applied electric field increases.when the thickness of the ER elastomers layer is increased,nat... |
