Bump Test Machine, Free Fall Type

Tarang Kinetics offers a Bump Test Machine, Free Fall Type (Low Force "g"). This computerised machine is a versatile test equipment to carry out bump tests in accordance with various IS, MIL-810F, DIN, EN, ISO, IEC, DEF and 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" and 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 machine is supported with Pentium PC based intelligent instrumentation system to control and monitor and analyse acquired acceleration waveform on 4 channels. The unit operates on 415/230 V ±10%, 50 Hz single phase AC and 3-phase 415 V 50 Hz.
System parameters:

• Acceleration - 3 g to 60 g
• Pulse duration - 3 ms to 18 ms
• Payload capacity - 1 kg to 1000 kg
• Number of bumps - unlimited
• Bump rate - 60 to 180 bumps per minute.
