摘　　要：柴 燃联合动力装置是大中型水面舰船的核心设备之一,本文在改进的柴 燃联合动力装置物理模拟实验台上,对主机切换过程中瞬时转速、瞬时扭矩和三S离合器中间滑移件位移信号进行测量,并利用小波分析对信号进行降噪处理,去除干扰,从中提取有用信息,获取不同切换方式下的有用信号,这更有利环境对实验结果的分析,并对主机切换过程的实验研究有重要意义。Combined Diesel or Gas Turbine(CODOG)Power Plant is one of the key devices in the main naval ship,in the paper the displacement signals of instantaneous torque?instantaneous rotate speed and the middle slippage piece on the S.S.S.clutch during the main engine changeover on the improved combined diesel or gas turbine power plant experiment rig are measured,the wavelet analysis was used to reduction the noise,and picked up the useful information,the signals of different changeover mode had obtained,it is propitious to analyze the experiment results,and it is of significance to proceed the experimant during the main engine changeover.
