Abstract:
In test of liquid propellant rocket engine．burr’S occurrence in the data curve of fre— quency signal such as flow rate and rotating speed of pump affects the accuracy of measured data． According to optimizing the sampling mode of frequency signal，a simulation method is adopted to reduce the occurring burr in this paper．The method mentioned has been verified in real test and the result shows that it can reduce the burr of the frequency curve effectively．
