摘要: 悬挂式复合材料动力设备基座是一种新型减振基座,主要通过延长振动传递路径和采用复合材料两个途径减小振动。针对基座的主要承重结构,设计并制备了玻璃钢复合材料立柱,并用实验和数值计算的方法分析了复合材料细观参数和立柱宏观参数对GFRP立柱的动力学特性影响。研究结果表明,铺层角度和纤维体积分数对GFRP立柱动力学特性影响较大,且改变奇数层铺层和偶数层铺层性能也不一致,立柱结构的宏观参数也会对立柱动力学特性有影响。研究结果可为悬挂式复合材料动力设备基座的设计和应用提供参考。

Abstract: The suspended composite power equipment pedestal is a new type of vibration-damping pedestal, which mainly reduces vibration by extending the vibration transmission path and using composites. Aiming at the main load-bearing structure of the pedestal, a glass fiber reinforced plastic (GFRP) composite column is designed and prepared, and the effects of the fine parameters of the composite and the macroscopic parameters of the column on the dynamics of the GFRP column are analyzed by experimental and numerical calculation methods. The results show that the layup angle and fiber volume fraction have a large influence on the dynamic characteristics of GFRP columns, and the performance is not consistent with changing odd and even layups, and the macro parameters of the column structure also have an influence on the dynamic characteristics of the columns. The results of the study can provide a reference for the design and application of suspended composite power plant pedestals.
