Low Force Vibration Shaker
Product Description

Electrodynamic Vibration Shaker System (Low Force Series)

Tarang's Electrodynamic Vibration Shaker Systems are capable to cater your test application requirements as per relevant ISO, IEC, JSS 55555 and MIL and other industrial Standards.

Low Force Series of Electrodynamic Vibration Shaker System is a combination of wide frequency range, high force and acceleration that serves to the general test requirements of various kinds. Its Industrial applications include:

  • Modal and structural analysis
  • Electronic assembly test
  • Laboratory experiments
  • R & D
  • Engineering institutions
  • Telecommunication equipments
  • Consumer electronics
  • Stress screening
  • Computer equipment testing
  • Product and package testing 
A number of optional accessories enable the system to match most of the test applications. Trunnion mounting enables both vertical and horizontal testing with slip table attachment.

Solid-state field power supply energizes the shakers electromagnet which is interlocked electronically to the amplifier unit and is placed within the unit to save space.

LOW FORCE SERIES of Electrodynamic Vibration Shaker System are vibration generating equipment, having wide frequency range providing a worthwhile testing environment for sinusoidal, shock and random vibration analysis in Automotive parts and system qualification testing, Avionics and military hardware testing, Satellite component testing, Product development & reliability, Telecom, Automobiles Industries, Stress screening and R&D laboratories etc as per relevant ISO, IEC, JSS 55555, MIL and other international Standards.

'Tarang' make Electrodynamic Vibration shaker system has a platform rigidly connected with a Drive Coil (Armature) positioned in DC magnetic field excited by AC signal generated by Digital Power Amplifier. When AC current flows in the drive coil, a force is generated which moves drive coil and attached platform vertically. This vibratory force is applied on the objects/specimens mounted on Shaker platform. This force can be used in the horizontal direction as well with the help of a slip table attachment. `Tarang' make Armature assembly utilize modern armature suspension systems which is Rolling strut type featuring low transverse motion. Reinforced SS inserts are provided on Armature platform to hold specimen/object to be tested.

The Digital Power Amplifier is a MOSFET/IGBT based Modular Type Class-D Switching to drive Electrodynamic Vibration Shaker System with high reliability, excellent durability and direct coupling to Shaker. Digital Amplifier Controller is a touch screen based very user-friendly interface equipped with self diagnostic and protection features such as cooling check, current supply check, field supply check etc. to avoid damage to Power Amplifier, Shaker and testing object due to malfunctioning or mis-operation. It generates the signal to drive the Power Modules and to give output to the Armature Coil.

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 but ensuring safety of device/object under test. Sinusoidal, shock, random and complex sinu-random vibration environment can be simulated using different software methodologies on the any Standard Digital Vibration Controller providing sinusoidal sweep, shock and random vibration test.
