内容简介
《动态系统可靠性分析--方法及航空航天 应用(英文版)(精)/大飞机出版工程》编著者吴 斌。
《动态系统可靠性分析--方法及航空航天 应用(英文版)(精)/大飞机出版工程》针对动态 系统的可靠性分析,阐述了一种新的优化技术,即针 对低频率谐 振动力载荷下的工程产品结构可靠性问题,使用综合 的快速概率方法,也即“扰动 算法+蒙特卡洛方法”。在针对两个航空航天实际工 程案例的应用中发现,运用此 方法能快速准确地解决失效面高非线性、大量计算强 度和动态系统高复杂度等原 有概率方法的应用困难。本书的出版填补了上对 快速概率方法的研究空 白。
本书可供从事民用飞机结构可靠性安全性工程设 计分析、试验、管理的技术人 员和相关专业的研究生使用。
