中国船舶工业总公司第九设计研究院和上海长宁橡胶制品厂共同研制成功的Ⅰ型系列减振器于1985年6月27日由上海市船舶工业公司和上海市供销合作社主持,在沪通过了产品鉴定。参加鉴定会的有来自高等院校、科研、设计、环保、应用等29个单位,49名代表。冲床上楼及其隔振问题是国内外正在研究的课题之一。本系列减振器适用于冲床隔振,振动加速度的隔振效率达90％以上,噪声降低3分贝(A)以上。同时也速用于其他产品垂直冲击干扰设备的减振。每只减振器承载(静载)1500～12000牛顿,静刚度为10000～85000牛顿/厘米,动刚度25000～
China Shipbuilding Industry Corporation Ninth Design and Research Institute and Shanghai Changning Rubber Products Factory jointly developed type Ⅰ series shock absorber on June 27, 1985 by the Shanghai Shipbuilding Industry and Shanghai Supply and Marketing Cooperatives hosted in Shanghai passed Product identification. There are 29 units and 49 representatives from colleges and universities, scientific research, design, environmental protection and application. Punch upstairs and its vibration isolation is one of the topics under study at home and abroad. This series of shock absorbers for punch vibration, vibration acceleration vibration isolation efficiency of 90% or more, the noise reduction of 3 dB (A) or more. At the same time, it is also used to reduce the vibration of vertical impact jamming equipment of other products. Each shock absorber carrying (static load) 1500 ~ 12000 Newton, static stiffness 10000 ~ 85000 Newton / cm, dynamic stiffness 25000 ~
