Tarang make Computerized bump test machine is a versatile test equipment to carry out bump tests in accordance with various IS, MIL-810F, DIN, EN, ISO, IEC, DEF & ASTM standards. The machine is used in product qualification testing, transient analysis of structures or models and fatigue tests on some systems and parts with an object to determine their suitability under repetitive BUMP environment (during transportation or in-service etc) and to assess structural integrity.

Free Fall type Bump Test Machine has a robust steel structure, this machine can be used for testing of test objects having weight from 50 Kg to 1000 Kg, with Acceleration from 3 "g" to 60 "g" & pulse duration from 3 ms to 18 ms. The machine is intended to reproduce the effects of repetitive bumps 60 to 180 bumps per minute likely to be experienced by components and equipment during transportation or when installed in various classes of vehicles. The machine is mounted on air springs to isolate from the ground so that no vibration passes to the building.

The mounting platform is lifted vertically through a Cam arrangement and is made to drop freely on the rubber pad placed on the anvil which provides the required acceleration level. The desired impact acceleration can be obtained by adjusting the free fall height of the mounting platform. Rubber pads are used to produce half-sine pulses, duration of pulse can be adjusted by changing the hardness and thickness of the rubber pads.

The Bump test machine is supported with Pentium PC based Intelligent Instrumentation system to control & monitor and analyze acquired acceleration waveform on 4 Channels. The unit operates on 415/230V ±10%, 50 Hz Single Phase AC & 3 Phase 415 V 50 Hz

System parameters
» Acceleration - 3'g' to 60'g'
» Pulse Duration - 3'ms' to 18'ms'
» Payload Capacity - 1Kg to 1000Kg
» No of Bumps - Unlimited
» Bump Rate - 60 to 180 bumps per minute

Tarang make Computerized Force Impact type Bump Test Machine is designed to cater the high acceleration and high pulse duration repetitive bump tests. The machine is used in product qualification testing, transient analysis of structures or models and fatigue tests on some systems and parts with an object to determine their suitability under repetitive BUMP environment (during transportation or in-service etc) and to assess structural integrity & stress screening.

Force Impact type Bump Test Machine has a robust steel structure that enables it to be used for testing of test objects having weights from 50 Kg to 1000 Kg, Acceleration from 3 "g" to 400 "g" & pulse duration from 3 ms to 30 ms. The machine is intended to reproduce the effects of repetitive bumps from 40 to 180 bumps per minute likely to be experienced by components and equipment during transportation or when installed in various classes of vehicles. The object mounting hole pattern of the platform is 100 X 100mmmatrix or as desired by the customer. An optional T-slot for mounting of test objects is also provided.

The mounting platform is lifted vertically through a Cam arrangement and is made to drop forcibly with the mechanical impact generating mechanism on the rubber pad placed on the anvil which provides the required acceleration level. The desired impact acceleration can be obtained by adjusting the drop height & mechanical impact generating force of the mounting platform. Rubber pads are used to produce half-sine pulses, and duration of half sine pulse shape can be adjusted by changing the hardness and thickness of the rubber pads.

The Bump test machine is supported with Pentium PC based Intelligent Instrumentation system to control & monitor and analyze acquired acceleration waveform on 4 Channels. The unit operates on 415/230V ±10%, 50 Hz Single Phase AC & 3 Phase 415 V 50 Hz

System parameters
» Acceleration - 3'g' to 400'g'
» Pulse Duration - 3'ms' to 30'ms'
» Payload Capacity - 1Kg to 1000Kg
» No of Bumps - Unlimited
» Bump Rate - 40 to 180 bumps per minute

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. Tarang PC based instrumentation system provides to control, monitor and waveform analysis for accurate, informative, dynamic test data of bump test machine.

Tarang PC based Intelligent Instrumentation system to drive the Cam mounted inside the machine. It regulates Bump Count, and Instrumentation Trigger etc. The unit is rigid, easy to handle & uses latest technology to control & read Bump Rate. To make the system more versatile a suitably designed LABVIEW based GUI programme to control, monitor and analyze acquired acceleration waveform of all the four channels simultaneously etc. with external PC with software to control it.

Tarang make Digital Bump Monitoring System, Model - TBSA 6001 is a Pentium PC desktop based intelligent instrumentation for on-line control & monitoring of bump vibration severity on an object mounted on Tarang make BUMP Test Machine, which is easy to operate and to set useful input parameters i.e. Number of Bump, Bump per minute, "g", data dump option. All relevant parameters viz. pulse height (acceleration), pulse duration, corresponding velocity change, Bump counts are displayed on screen in numerical format for all the four channels simultaneously. On-line zoom facility is provided to expand/compress the captured bump waveform. The facility is provided to store date & time stamped acceleration and waveform duration data in an ASCII file to view / process later on. A centronics compatible printer interface is provided to connect an external printer for hard copy of test results.

The system requires 230 V ±10%, 50 Hz AC supply for operation.
