一台高强化柴油机排气噪声有源控制实验研究

摘要

Exhaust noise is the main noise source of a dieselengine，especially to a high intensity diesel engine．It worsen work environment of ope rators， and it may lead some disease in long time．An adaptive active noise control syste m is designed to control exhaust noise of a high intensity diesel engine，the experimental results manifest the system is very efficient in controlling the noise ，and it enhances the fuel economy．%柴油机噪声使操作人员工作环境恶化，长期还危害操作人员的身体健康。排气噪声对柴油机整机噪声贡献很大，本文设计了一套自适应有源噪声控制（AdaptiveActive Noise Control）系统用于控制排气噪声，实验结果表明该系统效果良好。
