基础振动下直动式减压阀动态特性分析
The dynamic characteristics analysis of direct operated pressure reducing valve on fundamental vibration
摘要
Abstract
In order to focus on the impact of fundamental vibration on the performance of the TBM hydraulic components and provide theoretical basis for the optimal design of TBM hydraulic com-ponents ,mathematical model was established based on the operating principle of direct operated pressure reducing valve . The influences of different fundamental vibration amplitudes and fre-quencies on valve fluctuation characteristics were researched ,and the structural parameters influ-encing its pressure fluctuations were analyzed .The results indicate that fundamental vibration causes the valve outlet pressure fluctuations ,the fluctuation amplitudes increase with the excita-tion amplitudes .Pressure amplitude increases with frequency significantly when the excitation frequency is greater than 50 Hz .Reducing the backpressure chamber volume and diameter of the return channel can improve the valve dynamic stability .关键词
