Integration Design for the Optimum Positions of Propulsion Shafting System Bearings

探讨了轴承位置双向优化的必要性，基于轴系应有足够横向挠性即较小的轴承负荷影响系数和轴承负荷应尽可能平均分配的要求，建立了确定最优安装位置的数学模型。最后，探索了合适的优化计算方法，并进行了实船计算。

This paper first discusses the neCessity of the optimum locating for longitudinal -- vertical position Of the bearings simultaneously. The mathematical optimum model is presented, and the improvements are embodied in the elastic representation, minimization of the reaction influencenumber and even distribution of the bearing load. Finally, a ploper optimum method and an actual example is given.
