对水面舰艇纵向轴系游动端支座间隙设计的深化研究

Further study on the gap in the bearing at free of the longitudinal shafting of the surface naval ship

本文提出了一种新的纵向轴系游动端支座合理间隙设计计算方法。由于这种方法较客观地计及了舰艇中垂及中拱弯曲变形对纵向轴系游动端支座间隙的影响 ,因此 ,按这种方法计算 ,可使水面舰艇纵向轴系游动端支座间隙设计变得更安全。

The paper proposes a new calculation method for determining the reasonable gap in the bearing at free end of the longitudinal shafting. The method accounts the effect of sagging and hogging bending deformation of ship hull on this gap and can lead to obtain a more safe and more suitable gap in designing the longitudinal shafting for the surface naval ship.
