摘　　要：通过分析多种优化配置算法的优缺点,并结合大型结构的动态特性,提出一种混合优化算法,使传感器布置更加合理。以飞机侧翼结构为例进行传感器的优化配置,结果表明,采用优化算法计算得到的传感器配置方案,既能保证监测模态的完整性,又能使模态向量的空间交角最大。By analyzing the advantages and the disadvantages of several optimal algorithms and dynamic characteristic of large - scale structures, a new hybrid algorithm is presented, which is more reasonable in ranking the sensor locations. And the airfoil casing is used to apply and test this algorithm, the final results indicate that the arrangement through the new optimal method not only can retain the integrity of the target mode shapes, but guarantee the cross - orthogonality between the target modes.
