| Abstract: | The main sources of the interior noises of the tractor cab are analyzed.That the struc-tural-acoustic coupling noises in the cab are the principal factor is confirmed.Feasibility anda realizable way of dynamic optimization acoustic design of structural-acoustic coupling sys-tem of tractor cabs are probed in theory.The preceding theoretical analysis methods are veri-fied by experiments.The dynamic optimization acoustic design scheme of structural-acousticcoupling system of tractor cabs is proposed. |
