摘要
增压器噪声由气动噪声和机械噪声组成。对某型号增压器气动噪音和振动噪音进行研究,并预测增压器总噪音。对实物样机进行噪音测量,实测结果与预测结果相近。增压器噪声预测可作为增压器设计的重要环节。
Turbocharger noise consists of pneumatic noise and mechanical noise. The pneumatic noise and vibration noise of a type of supercharger is studied and the total noise of supercharger is predicted. The noise of the prototype is measured,and the actual measurement results are close to the predicted results. Turbocharger noise prediction can act as an important link in the supercharger design process.
