摘要: This study investigates the response frequency conversion characteristic of a nonlinear curved panel mounted with centre mass and sound radiations. A set coupled governing differential equations is up used to generate vibration responses, which are calculate corresponding radiated sounds. The vibration, levels, ratio antisymmetrical symmetrical mode responses plotted against excitation level compared experimental data. investigated from spectrums responses.
