摘要： 随着车辆舒适性要求的不断提高,对进气系统的声学性能要求也越来越高.首先,以声学理论为基础,应用可靠性计算方法,对车辆进气系统的概念设计方案进行声学可靠性评估;其次,基于可靠性综合评分分配法,结合给定的声学可靠性指标,重新对车辆进气系统进行声学可靠性设计,准确迅速地得到了各个消声元件的声学可靠性优化设计信息.因此,基于传递损失的声学可靠性设计在概念设计阶段可为车辆进气系统的消声元件的结构设计提供定量的依据,具有很高的工程应用价值.

Abstract: With the increasing need of vehicle's comfort ableness, the acoustic performance of vehicle intake system is further required. Based on the acoustic theory, the numerical method of reliability was applied to the acoustic reliability evaluation in the conceptual design of vehicle intake system. Then, based on the comprehensive score evaluation of reliability distribution in combination with the given index of acoustic reliability, the acoustic reliability of vehicle intake system was redesigned, thus getting the information on reliability optimization design of all muffler component for vehicle intake system rapidly and accurately. Therefore, the acoustic reliability design based on transfer loss can provide a reference quantitatively for the constructional design of muffler components of vehicle intake system in conceptual design, which is of significance to engineering practice.
