The present device can be used to perform a free vibration test of a bridge rigid model in a good natural wind field without a large wind tunnel apparatus, and the size of the test model is not restricted by the size of the wind tunnel, and therefore a large-scale model test can be realized. Compared with a traditional wind tunnel test method, the present device can not only greatly weaken the geometric nonlinearity during large-amplitude vibration, but also can solve the problem of an excessively high blocking rate in a large-amplitude vibration wind tunnel test, and thus is suitable for studying large-amplitude vibration. A wind deflection angle of the model can be easily adjusted by using the rotary table, such that the wind-resistant performance of the bridge at different wind deflection angles is conveniently and comprehensively studied, being more convenient than the traditional wind tunnel test.
