摘要
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.关键词
