摘要
Abstract
The gate is mainly used for retaining water and regulating the upstream and downstream water levels and is an important structure in hydraulic structures.To explore the finite element static distribution and natural vibration characteristics of the gate,a finite element static analysis was conducted on the Liu Laojian new gate.The stress distribution of the gate panel,main beam,edge beam,longitudinal beam,bottom beam and secondary beam was obtained.The results show that the maximum normal stress of the gate is 33.3 MPa,which is located at the middle and rear flange of the main beam span.The maximum normal stress,shear stress and reduced stress of the gate meet the stress requirements.The modes of the gate under the condition of no water and 7.5 m head are compared and analyzed.The second,third,fourth and fifth order natural vibration frequencies of the gate under the condition of 7.5m head are reduced to different degrees compared with the natural vibration frequencies of the gate under the condition of no water.The influence of fluid-structure interaction between the gate and the water body on the natural vibration of the gate cannot be ignored.关键词
