摘要
以某300 MW压缩空气储能电站空气压缩机组为依托,开展了机组刚性框架基础的动力性能试验研究,并分别与不考虑和考虑地基刚度影响的数值仿真计算结果进行对比。结果表明:300 MW空气压缩机组刚性框架基础具有良好的动力性能,振动位移峰值满足我国规范限值要求;以柱底固结模型进行计算指导结构设计是偏于安全的,但在评估高低频组合扰力作用的基础动力性能时,应考虑地基刚度的影响。研究成果可为高低频组合扰力作用的动力机器基础设计及相关工程应用提供参考。
The experimental study on the dynamic performance of rigid frame foundation of air compressor unit is carried out in this paper based on a 300 MW compressed air energy storage power station.The test results are compared with the numerical simulation results of the column bottom consolidation model and the numerical simulation results considering the influence of foundation stiffness.The results showed that the rigid frame foundation of the 300 MW air compressor unit has good dynamic performance,and the peak vibration displacement meets the limit requirements of Chinese regulations.Using the finite element analysis model with column bottom consolidation can guide structural design,but the influence of foundation stiffness should be considered when the dynamic performance of the foundation forced by high and low frequency combined disturbance is evaluated.The research results can provide reference for the design of air compressor unit foundations under high and low frequency combined disturbance effects.
