摘要
分析了水动力荷载与闸门振动特性 .采用实验模态分析验证有限元数值计算得到的闸门模态特性 ,并进行闸门结构的优化设计 .应用随机振动理论分析闸门结构的随机振动响应 .计算实例表明 ,优化闸门结构的动特性可有效地提高闸门的抗振性能 .
Characteristics of hydrodynamic load and gates vibration are analyzed. Modal characteristics of the gate calculated by FEM is verificated by experimental modal analysis, gate structure design is optimized, and random vibration responses of the gate structure are analyzed using random vibration theory. It can be seen from an actual work that the optimization of gates dynamic characteristics can effectively improve its anti vibration capacity.
