摘　　要：为更优地对结构进行动模态测试,该文提出采用粒子群算法对拾振传感器的布置位置进行优化的解决方案。首先对结构的振型测试进行介绍,重点介绍优化的需求和优化的技术流程,其次对目标函数的形式进行讲解,然后讲解粒子群的优化流程,最后以一个四跨连续刚构为案例对该文所提方法进行验证,结果表明,优化后的目标函数有较大程度的减少,说明优化后的位置可以更好地感知结构振动,研究可为结构模态测试提供依据。For better test of dynamic modal on structure,a particle swarm optimization(PSO)algorithm is adopted to optimize vibration-pick sensor location.First,the vibration mode test of the structure is introduced,focusing on the optimization requirements and optimization technical process.Secondly,the form of the objective function is explained,and then the optimization process of the particle swarm is explained.Finally,a four-span continuous rigid frame is used as a case to verify the proposed method.The results show that the optimized objective function is reduced to a large extent,which shows that the optimized position can better sense structural vibration,and the research can provide a basis for structural modal testing.
