ISTA 6 Amazon Electrodynamic Shaker Vibration Test Machine for Transportation Test
The drive signal from the Digital Signal Processing Controller is input to the amplifier. The Amplifier takes the low voltage (0-5 volts and milliamps) from the controller and converts it to higher voltages and currents (0-100+ volts and hundreds or thousands of amps) for the shaker.
The armature of the shaker is suspended in a strong magnetic field. The current from the amplifier flows through the driving coil attached to the moving element. A force is generated on the wire by the current flowing through the wire in a magnetic field. The suspended moving element is restrained and allowed to move only in axial direction. The motion of the table follows the characteristics of the current through armature driving coil. Sinusoidal current produces a sinusoidal motion, random currents produce random motion.
The movement of the table is sensed by the accelerometer (pick up transducer). In case of using charge accelerometer, it produces a charge measured in pc (10
coulombs). The signal conditioner or charge amplifier coverts the charge signal to a normalized voltage one for the controller. This can be anywhere from 1mV/g to 1000 mV/g. The conditioned signal is feed into the closed control loop from the charge amplifier to a pre-defined reference level. The controller continually adjusts the drive signal to the amplifier to maintain the reference level.
