Abstract

In this paper, the dynamic characterization of hybrid composite material of carbon-epoxy sandwiched by steel is presented from the rotor-bearing system perspective. The tensile and flexural strengths of the hybrid material are investigated followed by the detailed damping estimation using modal testing in cantilever mode and dynamic mechanical analysis in double cantilever mode. The experimental characterization results obtained in this work have fundamentally ascertained the mechanical and dynamic behavior of hybrid composite material for the intended application.

转子-轴承支撑系统混合复合材料的动力学特性

摘要

本文从转子-轴承系统的角度介绍了钢夹碳-环氧树脂混合复合材料的动力学特性。研究了混合材料的拉伸和弯曲强度，然后使用悬臂模式下的模态测试和双悬臂模式下的动态力学分析进行详细的阻尼估计。在这项工作中获得的实验表征结果从根本上确定了杂化复合材料在预期应用中的力学和动态行为。
