摘要： 土工二维振动离心机是岩土地震工程试验研究最有效的试验设备，转臂是支承和驱动吊篮、振动台、试验模型和配重等高速旋转并达到离心试验加速度要求的关键部件．常规土工离心机转臂结构已不满足二维振动试验工况要求．为了使离心机能在常规土工试验、一维振动试验和二维振动试验各工况下稳定运行，将其转臂设计成具有工字梁的焊接框架结构．在对该结构布局和工作原理介绍的基础上，针对某二维振动离心机技术指标，对转臂结构进行了优化设计，并对优化结构进行了力学分析．其结果表明，焊接的框架结构满足二维振动试验工况要求，是一种比较合理的土工二维振动离心机转臂结构．

Abstract: The two-dimensional geotechnical centrifugal shaker is the most effective test equipment in researches for geotechnical earthquake engineering， and the swing arm is the key component， which supports suspended baskets, shaking table, test model and trim block etc， and drives them rotate to achieve centrifugal test acceleration. The conventional geotechnical centrifuge's swing arm structure cannot meet the two-dimensional vibration test conditions. In order to make the two-dimensional geotechnical centrifugal shaker operate stably under different working conditions such as conventional soil tests, one-dimensional vibration tests and two-dimensional vibration tests， the swing arm was designed as welded frame structure which had I-beams. Aiming at the qualifications of a certain two-dimensional geotechnical centrifugal shaker， the swing arm was optimum designed while its structure layout and operating principle had been introduced. The results of mechanical analysis show that the welded frame structure is reasonable because it meets all of the two-dimensional geotechnical centrifugal shakers test condition requirements.
Key words: centrifugal shaker    swing arm    I-beam    frame structure
