Vibration Test System

DEV 440 [4000 To 6000 kgf]


System Description


Electro-dynamic Shakers simulate real-world environments to investigate dynamic endurance and ascertain reliability in select fields of vibration testing.

This low sturdy force rating are specially designed for testing of wide range of products, be it electronics, automotive and defence applications. This series shaker generates high velocity which is required for shock applications.

As a standard configuration, the shaker is supported on a frame with a trunnion assembly for 90 degree till. Shaker itself has pneumatic body isolation and is force-air-cooled by a centrifugal blower system which sucks air through the evenly spaced air guide path that is interlocked with the amplifier console for operational safety.



System Description

The shaker's electromagnet and moving element are energized by the direct current and alternating current supplies respectively generated and are electronically interlocked to the power amplifier drive console.

The solid-state Power Amplifier is an intelligent microcontroller based console in a movable rack version. It has a feather-touch user-friendly interface at the front panel to drive the respective Electro-dynamic Shaker.

The PC based Remote Link Module can be optionally used to remotely operate the complete vibration system. It is based on a chip-board microcontroller and is driven by software commands to communicate identical functions of the amplifier's control panel e.g. Gain, FPS, Cooling, Start-up and Shutdown. All the critical parameters like output voltage, current, temp., and all system interlocks are displayed simultaneously.
