对水面舰艇纵向轴系游动端支座间隙设计的深化研究

A Detailed Study on the Design of the Gap at the Movable Support of the Longitudinal Shafts of Surface Ships

通过系统的分析及研究表明，水面舰艇中垂及中拱弯曲变形对纵向轴系游动端支座间隙有一定的影响，尤其当纵向轴系被固定在上甲板或舰底时，这种影响会达到不容忽视的地步。本文提出一项新的纵向轴系游动端支座合理间隙设计计算公式。由于该公式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，用该公式计算，可使水面舰艇纵向轴系游动端支座间隙设计变得更安全、更切合实际。

A systematic study demonstrates that the sagging and hogging deformations of surface ships have some effect on the gap at the movable support of the longitudinal shafts, especially when the shofts are fixed at deck or bottom. In this paper. a new formula is proposed for calculating the appropriate gap at the movable support of the longitudinal shafts. Using this formula, the gap can be designed safer and more practicable because it has taken account of the effect of sagging and hogging deformation.
