一、概述由中国船舶工业总公司第七○四研究所与上海市松江橡胶制品厂联合研制的GD型橡胶隔振器,主要是为了解决船舶通风机、水泵、空压机等机械设备的隔振而设计的.产品系列有GD-100、GD-200、GD-400等规格.其特点:固有频率低、阻尼比适中、三向刚度接近、有较好的隔振效果、结构紧凑、可实现多向安装、耐环境条件性能较好等.经过各项性能测试和装机使用证明:符合船用隔振要求,并于1985年12月通过了由中船总公司船舶系统工程部组织的技术鉴定.
I. Overview The GD rubber isolator developed jointly by the 704 Institute of China State Shipbuilding Corporation and Shanghai Songjiang Rubber Products Factory is mainly designed to solve the problem of mechanical equipment such as ship ventilator, water pump and air compressor Vibration and design. Products have GD-100, GD-200, GD-400 and other specifications. Its characteristics: low natural frequency, moderate damping ratio, close to three-way stiffness, better vibration isolation effect, compact structure, To achieve multi-directional installation, good performance of resistance to environmental conditions, etc. After a variety of performance testing and installation of the use of proof: meet the requirements of marine vibration isolation, and in December 1985 adopted by the CSSC Ship Systems Engineering Division of the technical appraisal .
