Micron

Micron make Bump Testing Machine is a versatile test equipment to carry out Shock/Bump tests in accordance with section of JS55555 anad other relevant Defence standards. The machine is used for production qualification testing, transient analaysis of structures or models and fatigue tests on sub-systems and parts with an object to determine their suitability under repetitive Shock/Bump environment (during transportation or in-service etc.) and to assess their structural integrity.
The machine is fabricated with welded steel of sufficient rigidity to provide necessary mechanical strength. The table (platform) is lightweight, made of special alloy and having threaded holes at regular pitch to mount test objects. A provision is made to adjust the drop height by special electro-mechanical/pneumatic arrangement between table and elastomeric pad. In order to achieve desired pulse duration, elastomeric pads of suitable Bump rate. A digital counter is provided to count the nos. of Bumps and run the machine for specified time (Bump counts) in manual and controlled mode of operation. The nos. of Bumps can be set on the settable counter.
The Bump Test Stand is supported with Pentium PC Based Intelligent Instrumentation front-end to monitor and analyze acquired acceleration waveform. A piezoelectric accelerometer is used as a sensor for this purpose. The accelerometer has built in electronics, which converts the mechanical Bumps to the electrical pulses. These pulses are filtered in signal conditioner to eliminate unwanted harmonics. The processed signal is digitized, scaled and displayed on 19"/21" TFT colour monitor. The acceleratin level and time duration are automatically calculated and displayed. Facility of controlled zero interception (programmable cursor approach) is provided to calculate more accurate time duration. The measured data can be sent to a standard Centronics compatible printer. The unit operaates on 415 +/-10%, 50 Hz A.C.

We offer a wide range of Electro Dynamic Vibration Test System from +/-10 Kgf to +/-5000 Kgf force for every imaginable application in vibration simulation. The MEV series of Vibration Test System overcomes the limitations of inability to simulate the entire frequency range of the vibration environment.

The series of MEV vibration systems are the result of long experience in the designing and manufacturing of test systems. The principle that make MEV test system flexible and versatile is the use of close loop control. It provides the exciter with a control signal, which is changing in frequency between certain limits aat a pre-determined sweep rate. The signal is automatically adjusted to maintain a constant vibration level at the frequencies. This is achieved by using a control accelerometer mounted on exciter table in servo loop to provide a feed back signal to the controller. The difference between the command and input signal is used to continuous correction signal to the vibration. The flexibility and precision control provided by the close loop technique allow the user to determine/simulate the vibration environment quite accurately.
