摘要
理论计算了不锈钢城轨车辆薄板结构的振动及声辐射,通过仿真软件计算了加筋和附加阻尼后的薄板结构辐射声功率,通过加筋薄板声学试验,验证了计算和分析结果的准确性。
The paper calculates abstractly vibration and radiated sound power of the plate structure for stainless steel metro vehicle.The radiated sound power of plate structure after improved is validated by computer simulation.The experiments are carried out to verify the validity of the theoretical method and computer simulation.
