摘　　要：简要介绍多点正弦激励系统的工作原理。结合万安导墙模型动态特性试验 ,研究了激振器的安装和模态测试方法。对容易出现的不利因素的影响 ,提出了相应的解决方法。并在模型试验中较准确地找出了结构的固有频率、振型。The working principle of multi-point sine excitation system is simply introduced. Through the dynamic property model test for Wan'an Project's guide wall, the installation of exciter and test method for oscillating mode are studied. The relative solvable methods on easily appearing effects of disadvantageous factors are proposed. And the modal parameters of self oscillation frequency, vibration mode and damp are precisely found.
