“…Loads arise from propeller`s, engine`s sides and in case of shafting line itself and its auxiliary mechanisms operating conditions failure. There were cases when the shafting line increased vibration caused cracks in the ship`s aft part elements [3]. Therefore, the uninterrupted and reliable shaft line operation is an actual problem nowadays.…”

The work investigates the bearing piece boundary conditions influence on the shaft line operating state, with respect to elastic properties of stern-tube bearings. It is noted that the shaft line is a part of the ship’s power plant and it is a shaft system, located on the same axis. Performance criterion is the deflection of the concentrated load in the design scheme`s action point, modeling the propeller`s weight, bearing parts reactions and the natural frequency of linear lateral oscillations. The design scheme itself is a beam, resting on two elastic supports with a k stiffness factor, with concentrated load acting on the one end and three variants of the boundary conditions: pinched, hinged and sliding supports on another one. The results of calculations are given for different boundary conditions and the stiffness factors of elastic supports. The diagram of natural frequencies of linear lateral oscillations of ship`s shafting line is presented.

“…There is a concentrated load, that simulates the propeller`s weight at one end of the beam, pinched supporting pier on another one. In many works [3,4,[11][12][13] related to the shaft line calculus, it is attempted to get away from the standard design scheme and resort to the necessary changes:…”
