摘　　要：颤振模型设计是动力学反问题 ,其数学实质即广义特征值问题的反演。从反演可解性的基本理论出发 ,以某型号飞机高、低速颤振模型结构设计为背景 ,提出了模型结构设计必须遵循的准则。为减少模型结构设计的盲目性 ,提供了一个实用而有效的工具 ,并以具体的数值例子 ,说明了这个设计准则的实际应用。Structural design of flutter model is an inverse problem of dynamics Its essence for mathematics is the inversion of generalized eigenvalue problem Based on fundamental theory for solvability of inversion, a criterion that must be followed in structural design of flutter model is presented here The criterion in this paper has provided a practical and effective means for overcoming blindness of flutter model design In combination with high and low speed flutter model design for an aircraft,the necessity for analysis of feasibility is explained The application of the design criterion is illustrated with the help of numerical examples
