摘　　要：振动台是力学环境实验室开展检测任务的核心设备,按照其获得能量的形式分为电动振动台、机械振动台和液压振动台,随着科学技术的发展已研制出激光振动台。目前用得较多的是电动振动台,原因是它的频率高、波形好、控制方便。主要针对电动振动台低频振动出现的问题进行分析和讨论。Vibration table is the key equipment of mechanical environmental laboratory to carry out the test work. According to gaining energy, the vibration tables are divided into electric vibration table, mechanical vibration table and hydraulic vibration table. With the development of science and technology, the laser vibration table has been developed. At present, the electric vibration table is used most, because of their high frequency, good waveform and easy to control. This paper mainly analyzes and discusses the low-frequency vibration problem of the electric vibration table.
