车辆乘坐室内饰吸声的有限元分析

【摘要】 用有限元法计算了壁面有吸声材料的车辆乘坐室在实际行驶条件下的室内噪声响应，建立了某样车的乘坐室有限元分析模型。理论计算结果得到了试验结果的验证，可用于车辆乘坐室内饰吸声的动态设计与分析。更多还原

【Abstract】 The in-house noise response under practical driving condition of motor vehicle passenger housing with sound absorbent material on inner wall surface has heen calculated by means of finite element methcd, and finite elemellt analysis model is established for a certain sample vehicle. The result of the theoretic calculation has got test verification so that it may be used in dynamic state design and analysis of internal trimming sound absorbing of motor vehicle passenger housing.更多还原
