Abstract: |
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. |
