| 摘 要： | 基于有限元和边界元方法，运用ANSYS和SYSNOISE软件建立驾驶室声—固耦合有限元模型和声学边界元模型，计算在指定工况下壁板的振动和驾驶员右耳旁的声压级。在此基础上，进行面板声学贡献度分析，确定对驾驶员右耳声压贡献突出的壁板。通过采用沥青型阻尼材料对壁板进行减振降噪处理，有效地降低驾驶员右耳旁噪声。

| Abstract: | The sound-structure coupled finite element model and the acoustic boundary element model of a cab were presented by applying ANSYS and SYSNOISE codes respectively. Vibration of panels under the specified condition and sound pressure level at driver＇ s right ear was computed. According to the results, panel＇ s acoustic contribution was analyzed and the panels which have important contribution to the sound pressure at the driver＇ s right ear were confirmed. Applying the asphalt damping materials to the panels, the noise at driver＇ s right ear was effectively reduced. |
