High-temperature combined vibration test system "THV-216-A-600 C"

  

High-temperature combined vibration test system "THV-216-A-600 C" is designed for simultaneous testing of products and materials for resistance to high temperatures and vibrations in a wide frequency range. Structurally, complex consists of two parts, each of which, in turn, is divided into modules and subsystems:

1. High temperature furnace on the hydraulic lift.

High-temperature furnace is designed to stimulate the processes of exposure to high temperatures (from ambient temperature up to + 600 ° C) to the test objects.

High-temperature furnace is mounted on hydraulic lift to enable coupling of furnace to vibration test system in order to perform combined tests of the samples for simultaneous exposure to high temperatures and vibrations.

2. Vibration test system.

Vibration test system consists of electrodynamic shake table complete with magnesium alloy table and control system.

The electrodynamic vibration table includes:

Generator of vibrations, Power amplifier, Air cooling systems of vibration generator, Magnesium expansion table, Vibrotest control system.
