摘要
针对某款国产中吨位叉车机外辐射噪声严重超标的现状,应用试验方法进行噪声源识别,并计算各主要噪声源的声能占比。根据噪声源识别的基础,分别对发动机机体辐射噪声、排气噪声以及风扇散热系统噪声进行针对性的有效改进,最终的测试结果发现综合治理后的叉车达到了国标要求,司机舒适度有了显著提升。
Focus on noise problem of certain middle size forklift, use test method to identify the noise source and calculate each noise source sound energy proportion. Base on the noise identification, improve effectively on basic engine radiated noise, exhaust noise and fan cooling system noise, finally the test result shows the comprehensive improvement make the forklift noise achieve chinese standard requirement, greatly increase the operator ergonomics.
