【摘要】 为了更好满足地震计的振动测试需求,对振动台的波形失真度、横向运动比、台面不均匀度及稳定性等主要性能指标进行了测试分析。测试结果表明:该振动台具有较好的低频振动特性。利用低频标准套组对该振动台和中国计量科学研究院标准振动台进行比对分析,测试结果存在较小偏差。更多还原

【Abstract】 It is necessary to test and analyze the main performances of shake table,including waveform distortion,transverse vibration ratio,nonuniformity and stability,to better meet the demands of calibration for seismometers.Test results indicate that it has good low frequency characteristics.Deviation between testing data from this system and the reference values provided by National Institute of Metrology is minor.更多还原
