根据广义特征值扰动及其逆问题理论,借鉴结构矩阵摄动理论,利用逆求思想,提出一种动力优化设计逆摄动法。用以求解考虑强度、刚度、频率禁区、强迫振动等因素影响及以有限元法为分析手段的转子系统的复杂动力优化问题。将其与数学规划法或准则法以及结构摄动法相结合运用,尽可能地避免重分析,亦便于工程技术人员应用和发挥能动性。文后给出了若干典型算例及实例计算验证。本方法可推广用于其他机械系统或工程结构的动力优化设计
According to the perturbation of generalized eigenvalue and its inverse problem theory, referring to the theory of structural matrix perturbation and using the idea of inverse seeking, a dynamic optimal design inverse perturbation method is proposed. It is used to solve the complex dynamic optimization problem of rotor system considering the influence of strength, stiffness, frequency forbidden area, forced vibration and other factors and using the finite element method as the analysis method. It is used in combination with mathematical programming or guidelines and structural perturbation to avoid re-analysis as much as possible and to facilitate the application and activation of engineering and technical personnel. After the paper gives a number of typical examples and examples of calculation and verification. This method can be used to promote dynamic optimization of other mechanical systems or engineering structures
