一、名词术语A——横向加速度的幅度(米/秒~2);f——横向振动频率(赫);θ——在 xy 平面内的振动方向(度);TSR——横向灵敏度比;Z——被试加速度计的指向;Ez——被试加速度计的输出(伏);Sz——被试加速度计沿 OZ 方向的轴向灵敏度(伏·秒~2/米);OZ——被试加速度计的灵敏轴,垂直于安装面(见图1);O(TSR_(min))——横向灵敏度比最小的角度值(度);X,Y——横向监视用加速度计的指向;OX,OY——在水平面内的座标方向(见图1);E_X,E_y——分别代表 X,Y 两加速度计的输出
First, the terminology A - amplitude of lateral acceleration (m / s ~ 2); f - horizontal vibration frequency (Hz); θ - vibration direction in the xy plane (degrees); TSR - lateral sensitivity ratio; Z is the orientation of the accelerometer under test; Ez is the output of the accelerometer under test (V); Sz is the axial sensitivity of the accelerometer along the OZ direction (volts · sec ~ 2 / m); OZ - (TSR_ (min)) - lateral sensitivity ratio of the minimum angle value (degrees); X, Y - horizontal monitoring with the accelerometer pointing ; OX, OY - coordinates in the horizontal plane (see Figure 1); E_X, E_y-- represent the X, Y accelerometer output
