参数化大型客机方案实例库研究

Research on Case Base of Parameterized Large Civil Aircraft

为充分利用和借鉴已有的大型客机方案实例信息,建立了参数化大型客机方案实例库,并在一个开放式飞机总体设计环境中完成了方案实例三维建模和相关参数入库,提出了面向对象的参数化实例方法。在此基础上实现了对实例库中客机参数的管理、参数分析,并通过初始布局方案的模块化设计,为总体设计阶段新方案的快速设计及初步分析奠定了一定的基础。最后通过应用示例说明了实例库在总体设计阶段的运用。

In order to utilize and study more effectively information of existing examples of large civil aircraft entities,a case base of parameterized large civil aircraft is established,and in the open conceptual aircraft design system,the examples of three-dimensional modeling are completed and related parameters are stored in the case base.Then,the method of surface parameter to the object instance is proposed.On this basis,the management of aircraft parameters in the case base and parameter analysis is realized.In addition,a new method is proposed that can form a new layout project through parts modular design and adjustment.All this lay the foundation for the quick design and preliminary analysis of new programs in the concept design stage.Finally, an instance of application examples illustrates the use of case base in the overall design phase.
