【摘要】 详细介绍了成都理工大学自行研制的两向三自由度弹簧式地震模拟振动台的机械、液压、电气系统的构成、工作原理、技术指标、使用说明,以及使用过程中常见故障和问题的排除操作程序,研究结果为该系统的正常工作和试验的顺利进行提供了技术保障。研究结果表明该振动台以结构简单、容易操作、造价较低、维修简单、同一模型可进行多次振动试验,尤其对于地质体或结构破坏启动机制的模拟,波形仿真度高等特点,成为地质体或结构在地震荷载作用下破坏研究的重要试验平台。更多还原

【Abstract】 The paper elaborately introduces the structures,working principles,technical indexes,use instruction,the problems in the process of using and operation procedures for problems elimination of two to three freedom degree spring-typed earthquake simulation vibration table,the hydraulic and electrical systems invented independently by Chengdu University of Technology.The results of this research provide a technical secure for the normal operation and the successful experiment.The results show that this vibration table has the features of simple structure,easy to operate,low cost,simple repair,multiple times of vibration experiments by the same model,especially the simulation to geological body or geological structure destruction start mechanism,a high waveform simulation degree,and so on.This table will become an important experiment table for damage research for geological body or geological structure under the function of earthquake load.更多还原
