摘要
本文是对我院3m×4m地震模拟振动台的台面参数和系统技术指标进行的测试分析。测得了台面的摇摆频率、前4阶弯曲频率及振型。系统测试中的各项指标和允许偏差均参照国内有关专家草拟的国标《液压振动台技术条件》(初稿)。测试分析结果表明各项指标满足使用的要求。
This paper presents the resuts of the tests and analysis of the table paramet es and system characteristics on our 3m×4m seism simulating shaking table.The swing frequency,the frequency of the first four curves and mode of the shaking table are given.Each parameter of the shaking table is determined according to the nation- al specifications—《Hydraulic Shaking Table Technique Conditions》(first draft). These results show that our shaking table satisfies the requirements for use.
