| 摘 要： | 用试验方法研究了阀门的开启程度、支撑位置变化和管道内液体脉动对管道系统振动特性的影响．结果表明：由阀门开启程度引起的振动频率随着阀门开启程度的减小而增大；由可移动支撑位置改变引起的两个振动频率随着可移动支撑向中间的靠近而逐渐远离；由管道内液体脉动引起的振动频率随着可移动支撑向中间靠近和阀门开启程度的减小而减小． |
| 关 键 词： | 管道 振动特性 阀门 液体脉动 |

| Abstract: | An experiment is done on the vibrations of a pipe at different angles of the valve opening. Results show that vibration frequency increases with the valve opening. And when two movable supports close to each other the vibration frequencies gradually separate. Vibration frequency caused by the fluid pulsation decreases with the distance between two movable supports. |
| Keywords: | pipe vibration valve fluid pulsation |
