| Abstract: | A experimental investigation on the frequency characteristics and the transfer function of flexible joint swing nozzle is discribed in the paper. The measurement method and mathematical model presented have been practiced in the test of joint nozzles GF-1042 and GF-1043,and have been demonstrated in a computerized simulation test. The experimental and the analytical result agree well and the accuracy can meet the requirements in engineering. |
