Dynamic analysis using finite element method for a nonlinear spring-supported disk: Technique to reduce second-order distortion due to diaphragm shape
This research aims to reduce the second-order distortion due to diaphragm vibration. The quadratic term of the restoring force of nonlinear springs varies in the pulling and compression directions. Utilising this property, nonlinear springs are attached to the edge circumference of the simple disk m...

| Sumario: | This research aims to reduce the second-order distortion due to diaphragm vibration. The quadratic term of the restoring force of nonlinear springs varies in the pulling and compression directions. Utilising this property, nonlinear springs are attached to the edge circumference of the simple disk model of a diaphragm. The attachment directions of the springs are alternated in the negative and positive directions to reduce the second-order distortion due to diaphragm vibration. A nonlinear response analysis using the finite element method is demonstrated and the efficacy of the proposed technique is confirmed. |
