摘要
对2000kN高速阻尼器试验系统的组成、特点、功能进行了介绍,特别是试验台架结构。分析了在进行黏滞阻尼器试验时影响试验数据精度的因素,这些因素包括液压系统加载能力、加载台架的刚度、试件安装间隙和数据通道之间的采集时差等,并对这些因素进行了数值模拟,提出了解决措施。
Mechanical composing,features and main functions of a 2000kN high-speed damper testing system,especially the structure of the loading frame,are introduced.This testing system is an Electro-hydraulic Servo Load System.Various factors influencing the test precision are analyzed,which include the capacity of power supply,stiffness of the loading frame,installation gaps of specimen and the time gap of DAS channels,etc.Some factors affect the data precision are numerically simulated when testing a viscous damper,and several solutions about precision control are proposed.
