Abstract

Contemporary product design and process development is based on an iterative specify-evaluate-revise approach which is often time-intensive and therein non-responsive to customer needs. The engineering of a product incorporates numerous stages, involving conceptual through to detailed design. For small quantities or lot sizes (1-25 parts), the product design and process planning steps account for an inordinate share of the overall development cycle. An integrated geometric, performance analysis and materials processing evaluation environment for concurrent, multidisciplinary design is needed to not only address design-through-production efficiencies and costs but to enable more responsive product development cycles. The environment should enable the user to interactively evaluate alternative designs, not only of individual components or subsystems but combinatorial alternatives varying in materials, performance envelopes and sizing. All of these issues are particularly relevant to a new class of aircraft, an uninhabited air vehicle (UAV), which is unique in terms of its mission and its vehicle life, environmental constraints and components through system reliability and maintainability.
无人飞行器的多学科设计
当代产品设计和工艺开发是基于一种迭代的规格-评估-修改方法,这种方法通常是耗时的,并且对客户需求没有反应。产品的工程设计包括许多阶段,从概念设计到详细设计。对于小批量或批量(1-25个零件),产品设计和工艺规划步骤占整个开发周期的比例过高。需要一个集成的几何、性能分析和材料处理评估环境,用于并行的多学科设计,不仅要解决从设计到生产的效率和成本问题,还要实现更快的响应性产品开发周期。环境应使用户能够交互地评价备选设计,不仅是单个组件或子系统,而且是在材料、性能外壳和尺寸方面变化的组合备选方案。所有这些问题都与一种新型飞机特别相关,即无人飞行器(UAV),它在其任务和车辆寿命、环境约束以及系统可靠性和可维护性方面都是独一无二的。
