摘要:

在以往的设计中，由于只考虑了减压阀的静态特性，忽视了减压阀的动态特性，致使减压阀经常发生振动，出现噪声。用控制减压阀膜片有效面积的方法，成功地解决减压阀的动态性能和静态性能的设计问题。计算和实验比较证明，该方法是可行的。

Abstract:

The existing reducer design causes the reducer to vibrate and to make a noise usually,when considering of only static characteristic but neglecting of dynamic performance.Using a new method of controlling effective diaphragm area introduced in this paper,static and complex dynamic characteristic problems can be solved successfully.The computation and the experimental results were compared.The validity of the method was confirmed by the experimental results
