摘　　要：针对车辆发动机进气系统声学可靠性有时随着声学稳健性的提高而降低的情况,研究了基于声学可靠性的车辆发动机进气系统的声学稳健性设计方法.将管道声学理论、可靠性设计理论和稳健性设计理论相结合,以车辆发动机进气系统声学可靠性分析为前提,进行了车辆发动机进气系统声学稳健性优化.通过基于声学可靠性的车辆发动机进气系统的声学稳健性设计,能够获得车辆发动机进气系统声学设计参数优化信息,不仅满足了声学稳健性设计要求,还能满足声学可靠性设计要求,可为车辆发动机进气系统声学性能设计提供定量依据.Sometimes the acoustic reliability in the intake system of vehicle engine decreases with increasing acoustic robustness,and to solve the problem the reliability-based design of acoustic robustness was studied.Combining the theories of pipe acoustics,reliability design and robustness design together,taking the acoustic reliability analysis as a precondition,the acoustic robustness in the intake system of a vehicle engine was optimized.The acoustic robustness design based on acoustic reliability is therefore available to get the information on the optimized parameters in acoustics design of the intake system,thus meeting acoustic design requirements for both reliability and robustness,and providing a quantified reference for the design.
