摘要
本文对柔性喷管摆动频率特性及其传递函数进行了试验研究,提出测量方法与计算的数学模型.在FG—1042、FG—1043柔性接头的试验中作了实际应用,并在计算机上完成了仿真试验,对提出的测量方法和建立的数学模型作了验证,结果表明,计算结果符合规律,精度能够满足工程的要求.
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.
