摘要

The warship propulsion system faces various impacts underwater. The strong real-time varying and unpredictable abnormal shock significantly damage the normal work cycle of ship propulsion. This paper explores the spatial position of a bearing with two-liner structure after being impacted. Five typical waveform functions are constructed. Different types of shock waves are exerted onto the entire propulsion system. The effect of different parameters on anti-shock of the bearing under different operation conditions are explored. The influences of impact force, impact time span, and impact waveform on the shaft system are expounded. Researches indicate that transient impacts on the drive device are temporary. Shock wave forms are closely related to the vibration responses after being impacted. Investigations serve as guiding references for studying the trajectory behavior of underwater shaft systems subjected to abnormal impacts and explosions.
