摘要
根据夹层板理论建立具有等厚 SMA层的夹层矩形薄板的横向振动方程 ,利用复模量法分析 SMA的超弹性效应对板的稳态受迫振动响应的影响 ,利用 SMA分段线性应力 -应变模型简化 SMA的超弹性本构特征 ,通过数值计算分析结构的稳态响应特性和阻尼特性 。
The vibration responses and damping capacity of the sandwich panels with SMA layers are studied. The transverse vibration equation for a SMA sandwich panels is derived by using sandwich panel theory. The complex modulus approach is employed to predict the steady state vibration responses of the sandwich panel subjected to sinusoidal force. The piecewise linear model of stress-strain is used to describe superelastic constitutive behavior of SMA. The response characteristic and damping capacity of simply-supported sandwich panel are presented.\;
