The apsp produced abroad is made by numerical controlled machine tool, which has noise level of 71db ( a ), the apsp produced in our country is made in the method of exploratory which has noise level of 73db ( a ) and 75db ( a ). in order to analyze the influence of stator curve to noise, the author used tri - coordinate measuring instrument to measured exactly the inside surface of stator and got the straddling point coordinate, and made curve fitting by using matlab as language and studied the fitting effect and then worked out the equation of stator transition curve in return seeking, then comparied this method with the standard style and made the conclusion : the equation of atator transiting curve of apsp made by numerical controlled machine tool is close to theorical 5 power curve standard style, but compared with it, the stator transiting curve of apsp produced in exploratory has a major error. combining the testing results of noise, one can know that the qualily of stator transition curve play an importance to t he noise of the pump
國外生產的汽車動力轉向泵是用數控機床加工的，其噪聲值為71db （ a ） ，國內生產的汽車動力轉向泵是用靠模方法加工的，其噪聲值分別為73db （ a ）和75db （ a ） ，為了分析定子曲線對泵的噪聲的影響，本人用三坐標測量儀對定子內表面進行精密測量，獲得定子內表面的離散點坐標，以matlab語言為工具對離散點進行曲線擬合，觀察擬合效果，然後，用回歸方法求出了定子過渡曲線的方程，並把該方程與理論方程標準型進行了比較，得出如下結論：用數控機床生產的汽車動力轉向泵的定子過渡曲線方程非常接近理論5次曲線標準型，而用靠模方法加工的汽車動力轉向泵的定子過渡曲線與理論5次曲線標準型相比較，則存在著較大的誤差，結合噪聲測試結果可知，定子過渡曲線的優劣，對泵的噪聲大小有著重要的影響。 -
