| 摘 要： | 根据流体力学理论，建立了液体内悬臂梁阀片的动力学模型，给出了阀片基频的计算方法，分析了阀片结构参数、阀片与阀座间隙对液体内阀片基频的影响规律．结果表明，液体对悬臂梁阀的动态特性影响较大，随间隙的减小和阀片尺寸的增加，液体内阀片的基频大幅度降低．

| Abstract: | The kinetics mode was set up and the method was given out to calculate nature frequency of the underwater cantilever-valve based on hydromechanics theory. The influences of the cantilever dimensions and the gap between the cantilever-valve and the valve-body on the nature frequency of the cantilever-valve were analyzed. Results show that the liquid has great influence on the dynamics characteristic of the micro-cantilever valve. As a result, the nature frequency of the underwater cantilever decreased greatly with its dimensions increasing and the gap decreasing. |
