将有限元技术与模态综合理论相结合 ,研制了一套完整的用动态子结构法进行动态特性计算与研究的程序系统 ,为工程实际提供了一套实用性和通用性较强的计算软件。在微机上将双协调自由界面模态综合法应用于航空齿轮动态特性的研究 ,为结构动力修改或其它需要总刚阵及总质量阵的动态工程计算寻求了一种有效途径。
Combining finite element method with modal synthesis theory, a complete set of program system for dynamic characteristic calculation and research with dynamic substructure method was developed, which provided a set of practical and versatile calculation software for engineering practice . The research on the dynamic characteristics of aeronautical gear by applying the double co-ordination modal approach to free-form interface on microcomputer will find an effective way for dynamic engineering calculation of structural dynamic modification or other total rigid matrix and total mass matrix.
