Abstract
An experimental method of measuring acoustic surface radiation resistance is developed. The principle of the method is based on obtaining source velocity and field pressure generated by the source. To measure surface radiation resistance, measuring probe was developed and measuring system was set up. Then, major factors that affect measurement accuracy is discussed and great improvements are got. After that, experiments of measuring baffled circular piston were conducted to analyze its applicable frequency range. To verify actual application effect, experiments of measuring the tube and cylinder heads of a diesel engine were performed. The results show that this measuring system can obtain resistance values in the frequency range from 460 to 1900 Hz with high precision. The measuring sys-tem has features of simple operation, convenient use, and high accuracy. Therefore, it can be used to determine surface resistance matrix of various structures.
