摘要
根据统计能量分析的方法,建立国内某种商务车的SEA模型,在其室内噪声的控制和预测中,应用优化设计方法对隔声与吸声方法的使用进行了优化设计,SEA仿真结果表明,其降噪后的结果与实际中有着良好的一致性,所选择的降噪方法是可行的。
Mainly discussed about the established of the business car model with the theory statistical energy analysis (SEA), in the noise control the sound insulation and absorption are selected with mechanical engineering optimization design. The results of simulations evidence that the selected noise control method is feasible.
