动力机器框架式基础的隔振研究
STUDY ON VIBRATION FOR FRAME FOUNDATION IN POWER PLANT
In this paper,the local vibration problem of the space frame foundation of power plant in the LiaoNing is studied.Spring-damper components are added to the local of the frame foundation,the equations of motion for helical-spring foundation is derived. A FEM model is established and the structure’s frequency domain vibration response is obtained by the dynamic calculation of the FEM model.Meantime,the dynamic response results of the isolated frame foundation are compared with those of the non-isolated frame foundations.The numerical examples indicate that it’s a good way to control vibration by adding spring-damper components to the frame foundation in power plant,and also validate the correctness and feasibility of this method.
