摘要

基于纤维增强复合材料层、阻尼层和加筋层之间的应力传递关系，提出了一种新的动态分析模型，用于评价随机取向碳纳米管增强加筋复合材料阻尼板的动态特性。利用能量法和复模量理论推导了振动方程。通过实验和数值模拟验证了分析结果的正确性。此外，利用该模型研究了结构变量对动力特性的影响，包括模态损失因子和一阶固有频率。

Vibration characteristics of composite damping plate with randomly oriented carbon nanotube reinforced stiffeners

Based on stress transfer relationship of fiber reinforced composite layer, damping layer and stiffeners, this study presents a novel dynamic analytical model in order to evaluate the dynamic characteristics of a composite damping plate with randomly oriented carbon nanotube reinforced stiffeners. Both an energy method and complex modulus theory are used to derive the vibration equations. Experiments and numerical simulations are adopted for confirming the correctness of the analytical findings. Furthermore, the model is utilized to investigate the impact of structural variables on the dynamic properties, including the modal loss factor and first-order natural frequency.
