对GARTEUR飞机模型进行参数型修正过程的缩聚问题,参数的灵敏度问题及其参数修正的求解问题作了分析和探讨。在此基础上对飞机模型进行有限元建模和试验模态分析,得到分析模态和模态试验的前六阶模态,运用有限元数据和实测数据进行基于混合优化技术模型修正研究。该结果表明,方法对解决修正研究中的修正结果的不唯一问题及其精度问题有实际意义。
The polycondensation problem of parametric correction process of GARTEUR aircraft model, the sensitivity of parameters and the solution of its parameter correction are analyzed and discussed. On this basis, the finite element modeling and experimental modal analysis of the aircraft model are carried out. The first six modes of the modal and modal tests are analyzed. The finite element and measured data are used to study the model modification based on the hybrid optimization technique. This result shows that the method is of practical significance in solving the problem of non-uniqueness and its accuracy in the revised results.
