With regards to the cyclostationarity of gear vibration, a novel indicator based on cyclic spectral analysis is proposed to assess localized gear damage. The cyclic spectral density of amplitude modulation and frequency modulation signals is deduced, and its properties in joint cyclic frequency-frequency domain are summarized. The ratio between the sum of cyclic spectral density magnitude along frequency...
This paper explores the synthesis problems of a reconfigurable mechanism and its kinematic chains through an analytical process. Firstly, it presents a general procedure to synthesize the kinematic chains of an end-effector with the prescribed motion specifications, and then deduces the construction criteria of such chains. Any mechanism with a certain specified motions can be synthesized; and vice...
