多学科设计优化:载人潜水器设计的一种新工具

多学科优化作为一种新的设计方法,已经成功地应用在很多领域,如飞机制造,太空船,汽车制造等.传统的载人潜水器设计并不是一种最优的设计方法,并且在载人潜水器的设计过程中所要涉及多种技术学科.将多学科优化方法引进载人潜水器的设计,从而可以实现真正的设计优化.本文介绍了多学科优化的基本理论和方法,整体构架,并介绍了探索设计空间的算法.在对多学科优化设计方法理解的基础上,提出了在载人潜水器设计中如何应用的初步考虑.

Multidisciplinary Design Optimization (MDO):A promising tool for the design of HOV

MDO has been used for a variety of applications in such as aerospace,aircraft, and automobile industries as an efficient methodology of design optimization.The human occupied vehicle (HOV) design is related to several disciplines such as hydrodynamics,structural mechanics and control theory.There are the aims of maximizing performance under technology constrains and minimizing cost under performance constraints.However,the current design of HOV is the one that only is integrated the results of all disciplines,not an optimization design.With the traditional design approach, there is no guarantee that a systems-level focus will be taken and "feasibility"rather than "optimality" is commonly all that is achieved.To improve the HOV design and to solve the problem, application of multidisciplinary design optimization (MDO) is proposed.Using MDO methods can cast a HOV conceptual design problem into an optimization framework.This paper introduces the history of MDO, its theory and discusses the problem how to apply MDO in HOV design.
