讨论了在多学科设计优化过程中,层级系统、非层级系统以及它们的子系统之间的相互关系,并将混合系统分成四类.通过建立多学科设计优化过程中各子系统设计变量和目标函数的协同规则,研制了针对混合系统优化设计的多学科混合协同设计优化方法.将此优化方法应用到微机械陀螺的优化设计中,取得了满意的结果. In the process of multidisciplinary design optimization, the relationship between hierarchical systems, non-hierarchical systems and their subsystems is discussed and the hybrid systems are divided into four categories.By establishing the design variables and objectives of each subsystem in the multidisciplinary design optimization process, Function, and developed a multi-disciplinary hybrid collaborative design optimization method for the optimization design of hybrid systems.This optimization method is applied to the optimal design of the micromachined gyroscope, and satisfactory results have been obtained.
