摘要
鉴于可靠性与性能一体化设计有助于缩短无人机设计周期,提高设计水平,根据可靠性与性能一体化设计的三维空间设计思想,对其中涉及的关键技术进行了详细论述和研究。关键技术包括:使用性能参数数学描述可靠性函数和指标;可靠性与性能一体化设计的多学科设计优化;一体化设计中的不确定性分析。通过某无人机系统设计的简要过程,验证了可靠性与性能一体化设计的可行性。该研究为无人机系统设计的理论研究提供了一种宏观框架,为工程实践指出了一种技术途径。
For the advantage to save time of UAV design and improve design level, the concept of three-dimensional space design of integrated design of reliability and performance is used; Its key technologies include quantization reliability with performance parameters, muhidisciplinary design optimization of integrated design of reliability and performance, and uncertainty analyses of integrated design. Integrated design of reliability and performance is feasi-ble which is verified by design of a UAV. The study provides macro-frame of theory research and techno-approach of engineering of UAV design.
