摘要

本文对3d打印蜂窝芯和玻璃/碳纤维增强复合材料蒙皮的旋转夹层板的阻尼、振动和失稳特性进行了分析。层压复合材料是用真空辅助手铺法制造的，蜂窝芯是用3D打印机制造的。对3d打印蜂窝夹层复合材料的振动特性进行了实验研究。采用基于有限元法的高阶剪切变形理论（HSDT）推导了夹层板的控制方程。进一步研究了转速、长径比、芯厚、轮毂半径和设置角对3d打印蜂窝芯玻璃/碳纤维复合材料夹层板振动、阻尼和失稳特性的影响。从得到的结果可以看出，蒙皮层混杂纤维的增强对旋转3d打印蜂窝夹层板的振动、阻尼和失稳特性有很大影响。

Vibration damping and instability analysis of glass/carbon fiber reinforced sandwich plates with 3D printed honeycomb core under rotating condition

In this work, the damping, vibration, and instability characteristics of the rotating sandwich plate with a 3D-printed honeycomb core and glass/carbon fiber-reinforced composite skins are analyzed. The laminated composites are created using the vacuum-assisted hand layup method, and honeycomb cores are fabricated using a 3D printer. An experimental investigation was done to examine the vibrations of 3D-printed honeycomb sandwich composites. A finite element method-based higher-order shear deformation theory (HSDT) is used to obtain the governing equations for the sandwich plate. Further, a thorough parametric study is conducted to examine the effect of rotational speed, aspect ratio, core thickness, hub radius and setting angle on the vibration, damping, and instability characteristics of the glass/carbon fiber composite sandwich plate with a 3D-printed honeycomb core. From the obtained results, it can be concluded that the skin layer's hybrid fiber reinforcement greatly influences the vibration, damping, and instability characteristics of the rotating 3D-printed honeycomb sandwich plates.

期刊介绍： Thin-walled structures comprises an important and growing proportion of engineering construction with areas of application becoming increasingly diverse, ranging from aircraft, bridges, ships and oil rigs to storage vessels, industrial buildings and warehouses. Many factors, including cost and weight economy, new materials and processes and the growth of powerful methods of analysis have contributed to this growth, and led to the need for a journal which concentrates specifically on structures in which problems arise due to the thinness of the walls. This field includes cold– formed sections, plate and shell structures, reinforced plastics structures and aluminium structures, and is of importance in many branches of engineering. The primary criterion for consideration of papers in Thin–Walled Structures is that they must be concerned with thin–walled structures or the basic problems inherent in thin–walled structures. Provided this criterion is satisfied no restriction is placed on the type of construction, material or field of application. Papers on theory, experiment, design, etc., are published and it is expected that many papers will contain aspects of all three.
