초록

Alignment of marine engine shafting generally implies a judicious slope alignment of supporting bearings in order to achieve acceptable values of bearing reactions and shaft stresses for all deformation conditions of hull. Authors developed a computer program, which computes the bearing reaction forces, the bearing reaction influence numbers and etc, using quadruple integration method. And the results of calculation for a 26,000 DWT steam container carrier were in good agreements with those of foreign shipyard. Also they introduced the optimization technique of slope alignment combined technical economic basis, and as a result of comparing characteristics of shafting in case of straight alignment whit those in case of slope alignment, the latter was found to be much better than the former.
