Design of Shaped PVDF Radiation Mode Sensor and its Application in Active Structural Acoustic Control System
This paper presents a new strategy for the design of radiation mode sensors by using shaped PVDF films for one-dimension structures.Based on a modal approach,the shape ofa PVDF sensor is analytically determined in such a way that the output signal of the sensor is directly proportional to amplitude of a particular radiation mode.Other modes are filtered out.A general expression of the PVDF sensor shape is obtained.It is found that the modal sensor shape can be expressed as a function of the second spatial derivative of the structural mode shape function.Finally,with an example of a vibrating beam,the proposed PVDF radiation mode sensor is used in an active structural acoustic control system for reduction of the structural-borne noise.
