The Study On The Mobility Of Structure-Borne Source And Receiver In Stiffness Control Region

The mobility analysis of the structure board installed by machines is very important for predicting structure noise transmitting. The ability of machines' sending structure-borne sound to structure board is determined by both source descriptor and coupling function. The analysis and forecasting of machine source mobilities and structure board mobilities have become important tasks in structure-borne noise control engineering.In order to carry through the structure board mobility analysis ,this article use FEA method to calculate the self-mobilitises and transmit-mobilities of structure board under different kinds of install conditions .And also used tradition analysis functions to asis our's researchIn the end ,we use ANSYS engineering software and model of spring vibration to analyze the results, and get the changing conclusions by legeng.
