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
