PAGE PAGE I 摘 要 本课题主要完成的任务是完成对L53LD罗茨鼓风机隔振体系与隔振器材的选用与设计。风机振动会加速机械设备的老化与磨损，振动噪声影响工作环境，造成严重的噪声污染。通过对隔振技术的设计，能够克服以上存在的缺陷，并且提高生产率，符合绿色生产的宗旨。 本文详细介绍了罗茨鼓风机的工作原理与特点以及国内外风机发展状况与未来发展趋势，介绍了风机的一些振动基础知识和隔振措施，进行了Matlab仿真，最后对一些关键地方进行了计算与验算，绘制了隔振体系图、隔振器图和风机尺寸图。 本文对隔振台进行了计算，并最终确定了其尺寸与质量，并对隔振台、风机和电机进行了质心位置计算和质量惯性距计算，最终选用JG EQ EQ -4隔振器，每两个隔振器为一个支承点。 关键词：罗茨鼓风机；隔振系统；振动验算；质量惯性距 Abstract The main task is to complete the selection and design of the vibration isolation system and isolation equipment for the L53LD roots blower. The vibration of the roots blower will speed up the aging and wear of the machinery and equipment. Vibration and noise impact on the working environment that causing serious noise pollution. The design for isolator technology will be able to overcome these shortcomings and enhance the productivity that meet the aim of the green production. This paper describes the working principles and characteristics of the roots blower. Then describes the development at home and abroad and the development trend in the future. Introduced some basic knowledge of the vibration and vibration isolation measures. We also have done a Matlab simulation in orde to introduce the vibration theory. At last we have a computing and checking for a number of key areas in the paper .A vibration isolation system plan, a isolator plan and a fan size plan are drawed too. In this paper,isolator pedestal were calculated and ultimately determine its size and quality at last. The centroid location calculation and the quality of inertia calculationaer are did for the isolation pedestal, the fans and the motors. Finally we choose JG-4 isolator, two each isolator as a supporting point.
