CSIEM-40-300大型振动离心机的设想与关键技术
|
摘要
动力离心模型试验为国际公认的土动力学和岩土地震工程研究最先进、最有效的物理模拟手段。目前美、日各拥有一台大型振动离心机,而我国大型振动离心机设备目前为空白,这与我国地震高发环境、经济高速建设和地质复杂条件极不相称,为此中国地震局工程力学研究所拟建设一台大型振动离心机(CSIEM-40-300)。概述了美、日2台大型振动离心机设备结构特点;介绍了CSIEM-40-300振动离心机设想和功能特色:具有高容量、高负载、宽频带、大位移等特点,其中振动容量40 g-t,振动负载1300 kg;并分析了关键技术和难点:振动台是整个系统的研制核心,其关键技术和难点集中在作动器、动力源、导向支撑装置和控制系统设计。
Dynamic centrifuge modeling test is internationally acknowledged as the most advanced and the most effective physical simulation approach in the field of soil dynamics and geotechnical earthquake engineering.Currently,large-scale centrifugal shaker is respectively installed in the USA and Japan,yet none has been established in China,which doesn't fit China's seismic risks,rapid construction and complicated geotechnical conditions.Inview of this,a large-scale centrifugal shaker(CSIEM-40-300) is planned to be built in Institute of Engineering Mechanics of China Earthquake Administration.The authors present the structural features of the two centrifugal shakers in the USA and Japan,and introduces the design and functions of CSIEM-40-300 vibrating centrifuge,involving wide frequency range,large displacement,large shaking capacity of 40 g-t,and large shaking load of 1300 kg.Moreover,it's shown that actuator,power source,guiding and supporting devices,and control system are critical techniques and difficulties in designing the shaker,which is the core of developing a large centrifugalshaker.
