船舶轴系的计算机辅助设计?xml:namespace
[摘要]船舶轴系是船舶动力装置中的重要组成部分,承担着将主机发出的功率传递给螺旋桨,再将螺旋桨产生的轴向推力传递给船体实现推船航行的目的.因此在船舶航行中起着重要作用.

[Absract] :The vessel shaft system forms an important part of the vessel power installation.Bearing the responsibility of passing the main engine's power output onto the turbine,then passing the turbine's axial thrust power to the hull of the vessel and completes the aim of propulsion the vessel to go forward.Therefore it plays an important role in vessel propelling.
轴系在运转中产生的负荷和应力十分复杂,工作条件十分恶劣,因而轴系设计合理与否直接影响到整个船舶的航行性能.
The load and stress produced from the turning of the shaft system are very complicated and a very poor working condition.Therefore whether the shaft system is reasonable has a direct effect on the entire vessel's sailing performance.
船舶轴系设计是船舶动力设计中的重要环节,它包括确定轴系轴径、轴系设计与强度校核、轴系传动设备的计算与选型.
Vessel's shaft system design is an important part of the vessel power design,which includes making sure of the exact axle diameter of the shaft system,shaft system design and intensity adjustment,calculation of the shaft system's power transfer installation and model selection.
轴系总体设计必须从船、机、桨的配合特性出发,合理地选配船、机、桨、传动设备的特性参数,实现船、机、传动设备、轴系、桨的最佳配合,保证船、机、桨在最佳状态下运行,即实现推进装置能量的最佳转换.
The overall design of the shaft system must be started from the combined characteristics of the vessel,engine and the turbine.Characteristic parameters of the vessel,engine and the turbine installation must be reasonably selected to achieve the best combination of the vessel,engine,power transfer installation,shaft system and the turbine.Ensures the vessel,engine and turbine's best operation,which would also mean achieving the best conversion of the propulsion system energy.
传统的方法是采用人工设计和计算的,由于船舶轴系的设计是一项复杂的工作,涉及到轴系的布置、轴承的受力分析和计算,螺旋桨的推力性能计算以及相关设备的匹配等诸多问题和内容,需要大量资料和计算,如果是手工来计算与设计,必然会效率低、周期长,实际的可选方案也会比较少.
The traditional methods were using manual design and calculation.For vessel shaft system design is a complicated work,involving the arrangement of the shaft system,analysis and calculation of the bearing power,the turbine's thrust performance calculation and its related installations' combination and so on details,which requires a huge amount of information and calculations.If manually designed and calculated,which would certainly have low performance and with long cycles,and their actual selectable programs would also be comparatively less.
采用计算机进行辅助优化设计,有效的解决了效率低的问题
Use of computer aided calculation carrying out the assistance of optimized design,would effectively solve the problems of inefficiency.
