The simplified vibration model of the upper rack of a suspension hydrogenerator was set up .By making use of the influence coefficient method to establish the differential equations of motion of the upper rack ,the relationship of stiffness and mass with the upper rack vibration frequency was presented ,and a simple and quick estimation method of the upper rack's radial stiffness was found out .It is validated that the method has a certain of accuracy and usefulness by comparing it with the results obtained from the traditional calculation method .
