船舶纵向轴系游动端支座间隙的优化设计

本文提出了一项新的纵向轴系游动端支座间隙优化设计计算公式。由于该公式较客观地计及了船舶中垂及中拱弯曲变对纵向轴系游动端支座间隙的影响，因此按该公式计算，可使航船纵向轴系游动端支座间隙设计变得更安全、更切合实际。

OPTIMAL DESIGN OF THE CLEARANCE FOR THE MOVABLE END SUPPORT OF THE SHIP LONGITUDINAL SHAFTING

It has been proved by systematic analysis and research that the sagging and hogging bending deformation of the navigating ship will exert a certain effect on the clearance of the movable end support of the ship longitudinal shaffings, which should not be negligibie especially for the longitudinal shaftings installed on the upper deck or the bottom. The author of this article has proposed a new calculation formula for designing optimally the clearance of the movable end support of the longitudinal shaftings. Because the formula includes more objectively the effect of the sagging and hogging bending deformation of the navigating ship on the clearance of the movable end support of longitudinal shattings, the caiculating according to the formula will make the clearance design of the movable end support of the ship longitudinal shallings hecome safer and more suitable to actual conditions.
