摘　　要：介绍了以健康监测与诊断研究为目的的悬索桥结构模型试验设计。根据悬索桥的结构特点,建立了考虑横向联结系的三维有限元模型;然后采用ANSYS有限元分析程序对模型的动力特性进行了预分析,获得了模型的自振频率和振型,进一步验证模型试验的可行性,为进行更深层次的试验研究奠定了基础。The paper introduces the design of suspension bridge trial model for health monitoring and diagnosis. In terms of structural characteristics of suspension bridge, the three - dimentional finite model for lateral bracing system is established. Then the finite element program ANSYS is adopted to make a preanalysis of model dynamic property, reaping the natural frequency of vibration for model and the vibration type, further verificating the feasibility of model trial, which lay a foundation for deep study of bridge＇ s health.
