摘要
水电站主厂房是由下部的上部框架与大体积混凝土等结构组成综合体,结合布仑口-公格尔水电站工程的电站厂房,采用ANSYS软件,提取主厂房结构的前30阶振动频率和振型,与运行期机组干扰振源频率进行共振复核分析。分析成果表明:当电站厂房结构高频区与低频区的错开度大于30%时,厂房基本不会发生共振的危险,共振复核可以满足要求,这也表明布伦口主厂房整体结构布置合理。
The main powerhouse of hydropower station is a complex composed of lower upper frame and mass concrete.Taking the powerhouse of Bulunkou Hydropower Station as an example,this paper uses ANSYS software to extract the first 30 vibration frequencies and modes of the main powerhouse structure and carry out resonance re-check analysis with the vibration source frequency of unit interference during operation.The results show that when the staggering degree between high-frequency and low-frequency areas of power house structure is more than 30%,there is no danger of resonance in power house.The resonance review can satisfy the requirements,which also indicates that the overall structure layout of Bulunkou main powerhouse is reasonable.
