[Objectives] In order to solve the problem of the longitudinal vibration of submarine propulsion shafting. [Methods] complex submarine propulsion shafting is simplified to a uniform stepped shaft continuum model. Wave Propagation Analysis (WPA) is used and the longitudinal vibration transfer relationship of each axis is deduced. Combined with the actual propulsion shafting boundary co... https://homehardware4ues.shop/product-category/sausage/
