Abstract: 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.
