Salient Features:
The Pneumatic Shock Test Machine is designed to produce half-sine shock pulses in the vertical direction using compressed air to force the platform to impact on the shock machine base. Elastomeric pads are used between the platform and base frame of the impact area to produce half- Sine pulses, lead pellets for saw tooth Pulses, and pneumatic cylinders for square pulses. The Drop height and the air pressure are responsible to accelerate the platform to generate the magnitude of the shock pulses.
The basic structure of the machine is heavy steel Welded with reinforced concrete which will not deteriorate under repeated shocks. The structure contains sufficient Mass to produce kinetic energy so that no supplementary counterweight will be required. Shock Test in accordance with IS, IEC, JSS 55555 MIL-810, ASTM etc.
The drop height and the air pressure are responsible to generate the desired acceleration. The different designs of the half-sine saw tooth and square wave pulse programmers are used to get the desired pulse shape and pulse duration.
The platform is supported and guided by the LB RODS to maintain its balance. The lifting of the platform is done by pneumatic cylinders; the drop height is determined by the desired acceleration level. In a shock test due to the renounce action secondary shocks may occur, which are totally unacceptable by most of the test standards. Fail-safe brakes are used as a rebounded brake and as a quick-release device to avoid secondary and tertiary shocks. The shock test machine is isolated from the ground by heavy-duty air spring and shock absorbers.
The Shock test machine is supported by a PC based intelligent Instrumentation system to control, monitor, and analyze acquired shock test waveforms. The system has 4 channels to monitor the shock pulses generated which are expandable up to 16 channels & more.
PC Based instrumentation System
The measurement of a shock pulse has become a highly specialized area of dynamic testing. The increased demands of the testing industry for accurate, informative, dynamic test data have established the basic requirements for instrument performance.
M/s Environment Equipments PC based instrumentation system provides to control, monitor, and waveform analysis for accurate, informative, dynamic test data of shock test machine. The control of the machine is very user friendly and incorporates various safety interlocks for the safe operation of the machine. The test report of any test performed can be viewed and printed easily. The shock analysis software is specially designed for the analysis of waveforms generated.
