Abstract

In this paper, the first attempt has been made to investigate the performance of the active constrained layer damping system in the thermal environment. For such investigation, a skew laminated composite sandwich plate with carbon nanotube-reinforced composite core is considered. The nonlinear strain-displacement relations are employed to generate the initial-stress stiffness matrix and the mechanical stiffness matrices using linear strain-displacement relations. The negative velocity feedback control-law is used to control the first few modes of the vibrating sandwich plate. Comprehensive investigation has been carried out to understand influence of geometric and material parameters on the damping performance of the system.

摘要

在本文中，首次尝试研究热环境中主动约束层阻尼系统的性能。对于此类研究，考虑了具有碳纳米管增强复合芯的斜层压复合夹层板。非线性应变-位移关系用于生成初始应力刚度矩阵和使用线性应​​变-位移关系的机械刚度矩阵。负速度反馈控制律用于控制振动夹层板的前几个模态。已经进行了全面的调查，以了解几何和材料参数对系统阻尼性能的影响。
