论文部分内容阅读
一、符号A——加速度幅度(米/秒~2);a——瞬时加速度(米/秒~2);D——位移幅度(米);d——瞬时位移(米);f——频率(赫);L——长度(米);n——线对数,米(米~(-1));p——百分比失真度;s——传感器灵敏度(伏·秒~2/米);η——每周期的脉冲数;θ——角度(弧度);λ——光波波长(米);ξ——百分比误差;τ——周期(秒);φ——角度(弧度)。二、振动台图1(略)和图2表示振动台。参考加速度计与被校准的拾振器装在镁制连接器的两边。参考加速度计系统是一伺服型加速度计和一放大器。
A - acceleration (m / s ~ 2); D - displacement amplitude (m); d - instantaneous displacement (m); f - Frequency (hertz); L-- length in meters; n-- logarithm in meters in meters (-1); p-- percentage distortion; s-- sensor sensitivity ); η - number of pulses per cycle; θ - angle in radians; λ - wavelength of light in meters; ξ - percentage error; τ - period in seconds; φ - angle in radians. Second, the vibration table Figure 1 (omitted) and Figure 2 shows the shaking table. The reference accelerometer and the vibrator to be calibrated are mounted on either side of the magnesium connector. The reference accelerometer system is a servo-type accelerometer and an amplifier.
