Electro-Dynamic Shaker
Our system consists of Drive Coil (Armature) positioned in direct current magnetic field excited by alternating current signal generated by Digital Power Amplifier. This generates a force making the drive coil to move as per the magnitude and frequency of the signal. This vibratory force is applied on the objects/specimens mounted on Shaker platform. The armature assembly utilize modern armature suspension systems which is Rolling strut type featuring low transverse motion.
Capable to perform tests in accordance with various standards eg. IS, MIL, DIN, ISO, EN, IEC, DEF, JSS 55555 & ASTM etc.
Power Amplifier
The Digital Power Amplifier is a MOSFET/IGBT based
Modular Type Class-D Switching interlocked with the
shaker. Digital Amplifier Controller is a
microcontroller, colour touch screen based userfriendly
interface equipped with self-diagnostic,
calibration and protection features which gets the
input signal from vibration controller and controls the
alternating current amplitude and frequency
accordingly.
The remote operation module can be optionally used
to remotely operate the complete Vibration Test
System.
Vibration Test Force Calculations
Vibration Controller
The Digital Vibration controller is used to simulate actual field vibration conditions at test laboratory in a controlled manner so as to reproduce the same vibration atmosphere.
The controller is capable of full control and analysis applications for sine, resonance & dwell, random, classical shock, random-on-random, sine-on-random, shock SRS, vibro-shock and field data replication.
Head Expander and Slip Tables
Our range of wide variety of head expanders and slip tables provides various possibilities to increase the effective mounting surface and orientation of the direction of test.
Mg Alloy is used for the construction of head expander s and slip tables to ensure minimal weight thereby being more suitable to the existing force of the system.
