In order to solve the problem in accurate identification of dynamic load of marine propulsion shafting bearings, this paper proposes a kind of frequency-domain inverse identification method based on inversion of frequency response functions by using full measured data as well as the corresponding data processing and evaluation methods. Then, on the propulsion shafting vibration test platform, radial bearing dynamic load identification tests under three types of external excitation were carried out to verify the proposed method. The test results show that the identification results of bearing dynamic load under unbalanced, random vibration and impulse excitation are consistent with the trends of amplitude-frequency and phase-frequency curves of measured results in the frequency band of 10 Hz-1 kHz, with a high degree of coincidence, and that in the frequency band of 10 Hz-1 kHz, the identification errors of bearing dynamic load are 0.21-3.5 dB under unbalanced excitation, 2.03-2.53 dB under random vibration excitation and 2.16-4.64 dB under pulse excitation, which proves that the inverse identification method is feasible and accurate.

本文针对船舶推进轴系轴承动载荷准确识别的难题开展研究,提出一种基于频响函数求逆并采用全实测数据的频域反演识别方法及相应的数据处理和评价方法;然后,针对推进轴系振动试验台架,开展三种类型外激励作用下的径向轴承动载荷反演试验进行验证。试验结果表明:不平衡、随机振动、脉冲激励下轴承动载荷的反演识别结果与直接测量结果在10 Hz~1 kHz频带内的幅频和相频曲线趋势一致,吻合度高;10 Hz~1 kHz频带内,不平衡激励下的轴承动载荷反演误差为0.21~3.5 dB,随机振动激励下为2.03~2.53 dB,脉冲激励下为2.16~4.64 dB,验证了反演识别方法的可行性和准确性。
