超低频振动实验室设计及应用
Design and Application of Ultra-low Frequency Vibration Laboratory
摘要
Abstract
According to the current research status and application requirements of ultra-low frequency vibration standard devices, a vibration standard device is set up in Sichuan Earthquake Agency, whose frequency range is from 0.002 Hz to 160 Hz, and amplitude of peak to peak is 0.1m, and load is 15 kg, and waveform distortion is less than 1%. The paper analyzed the design proposal and parameter selection for the ultra-low frequency vibration standard laboratory, and introduced in detail the structure of the device and the design of the base. Finally, the test results show that the device could meet the demand of calibrating seismometers in our bureau.关键词
