摘要
系统研究某微型客车因发动机、传动系振动及路面不平度激励引起的车内噪声的控制问题。通过试验分析 ,识别了主要声源 ,研究了车内声传递特性 ,确定了对车内噪声有较大贡献的车身板件 ,为进一步改善该车的声学特性而进行优化设计提供了基础。
This paper presents a systematic and practical research on the mini bus interior noise due to the engine,transmission system vibration and road irregularity excitation.Based on the experiential analysis,it also identified the main noise source,studied the sound transmission properties and determined the body parts which produced more serious noise inside the bus.This research provides a basis for the optimum design for effectively improving the bus interior acoustics characteristics.
