履带拖拉机噪声分析及控制技术研究

Study of Noise Analysis and Control Technology of Crawler Tractor

通过对履带拖拉机驾驶员耳旁噪声、静态环境噪声及部件噪声的测量和分析,采取多种改进措施,经过再次测试验证,各项指标明显优于国家标准要求,满足OECD认证,证明采取的措施是有效的。

Through the measurement and analysis of ear noise of driver,static ambient noise and component noise of the crawler tractor,many improvement measures were adopted.Many test validations show that the pivotal indicators are better than the requirement of national standards,and meet OECD certification,and which proves that the measures taken are effective.
