CVC (Combined Vibration and Climatic) Test System simulates real-field environments to investigate dynamic endurance and ascertain reliability in select fields of vibration testing.
This kind of test systems is specially designed for testing of wide range of products for Defence and Aerospace applications.
Shaker has pneumatic body isolation with auto body centering system required for integration with CATH Chamber and is water cooled by a close loop water cooling system which supplies distill water thru’ the hollow conductors of field and armature coils and 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.
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.
