SUPPLY, INSTALLATION,

TESTING, & COMMISSIONING

OF ELECTRO-DYNAMIC

VIBRATION SHAKER SYSTEM



Preamble

LPSC,Bangalore is engaged in design, development and realization of satellite

propulsion system for Indian space programme. Satellite propulsion system and its

subsystems are subjected to various environmental tests such as vibration tests, thermo

vacuum tests and acoustic tests etc. as part of design validation, qualification and flight

acceptance requirements. The satellite propulsion systems are designed with optimum

design margins. Vibration testing is one of the important environmental test being carried

out on satellite propulsion system components.

Vibration tests are carried out using vibration shaker systems comprising

ofelectrodynamic shaker, slip-table, power amplifier, field power supply, cooling units, and

hydraulic supply units.

The electro dynamic shakers systems used for testing satellite propulsion systems

and its subsystems have to meet stringent aerospace test requirements. The shaker system

should be highly reliable and of high precision. The system has to function uninterruptedly,

with minimum time lost in maintenance.

The essential requirements for electro dynamic shaker systems for testing satellite

propulsion system components are:

� Low Distortion � Low Cross axial Response � Low noise � High over turning moment restraint � Large Dynamic Range. � Precise alignment between shaker-slip table � High pressure hydro static bearing guidance for slip-table � Safety interlocks considering machine and the specimen under test.

Offers are invited from the reputed suppliers who h ave supplied similar systems, which have established heritage fo r testing aerospace systems.
