Vibration Test System

DEV 180 [400 To 600 kgf]


Vibration Test System Description


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

This low force range of shakers are specially designed for testing of small electronics and mechanical objects and for conducting experiments in engineering institutes .



System Description

As a standard configuration, the shaker is supported on a frame with a trunnion assembly for 90 degree till. It 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.

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.

Salient Features
