近日,徐工研究院承担的5个减振降噪项目相继结题,项目通过研究徐工XE470C型挖掘机、QY70K-I型汽车起重机、XM101K型铣刨机、CV122型压路机、GR 180D型平地机的减振降噪技术,显著地改善了设备的振动和噪声性能。其中铣刨机、压路机和平地机减振降噪项目的技术成果优于了国际标杆产品和欧盟CE认证噪声限值,达到国际先进水平。在减振降噪项目的研究过程中,徐工攻克了噪声源识别,消声器优化设计,风扇散热器匹配优化,发动机悬置测试评
Recently, Xugong Research Institute has undertaken five vibration and noise reduction projects have been concluded, the project through the research XCMG XE470C excavators, QY70K-I type truck crane, XM101K milling machine, CV122 roller, GR 180D grader Vibration and noise reduction technology, significantly improved the vibration and noise performance of equipment. The technical achievements of vibration and noise reduction projects of milling machines, road rollers and graders are superior to the international benchmark products and the noise limits of the EU CE certification, reaching the international advanced level. In the study of vibration and noise reduction project, Xugong overcome the noise source identification, muffler optimization design, fan radiator matching optimization, engine mount test evaluation
