Bump Test Machine, Force Impact Type

Tarang Kinetics offers a Bump Test Machine, Force Impact Type (High Force "g"). This computerised 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 and stress screening. The 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" and 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 100mm matrix 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 and 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 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.
