摘要
设计一款结构简单、易于加工的狭缝谐振腔以降低涡轮增压器whoosh噪声。本文以传递损失为评价指标,根据公式设计出新的狭缝谐振腔之后,经过数值计算以及试验验证,均证明其可靠性。最后进行上车试验,试验结果表明,该款狭缝谐振腔可以有效地降低涡轮增压的whoosh噪声。
Design a new resonant that is simple and easy processing to reduce the whoosh of the turbocharger noise.Take transmission loss as the evaluation index.There are numerical simulation calculation and test verification used to prove its reliability after the design of a new slit resonator.Finally,it is an experiment on the vehicle,the experimental results show that the slit resonator can reduce the whoosh noise of turbocharger effectively.
