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。 Finite element method was used to calculate the indoor noise response of the vehicle seat with sound absorbing material on the wall under actual driving conditions. The finite element analysis model of the passenger compartment of a certain vehicle was established. The theoretical calculation results have been verified by the test results and can be used in the dynamic design and analysis of vehicle interior sound absorption.
