To Predict a Shock Pulse using Non Linear Dynamic Model of Rubber Waveform Generator

Shock absorption capability of corrugated ring yield mount subjected to high impact loading

“…To get the higher value of shock applied, the DTM table is fallen from 610 mm height with jerk. The Drop Machine (DTM) has a height of maximum 24 inches, therefore, to have a higher value of impact, it is given some initial velocity [ 18 ]. An initial jerk is given to the drop table to get a higher value of impact.…”

“…The IR sensor is installed on the base plate, and it actuates when the drop table passes through it. When the drop table crossed it, the IR triggers and once this turns on then accelerometers begin to take a reading during this time interval [ 18 ] [ 25 ]. It is important to mention that all the items during the test are installed rigidly so that load distribution is as uniform as possible.…”

“…Teruna et al [ 17 ] checked the response of various steel dampers in the structure in case of an earthquake. Iqbal et al, [ 18 ] used the drop test machine to study the various types of shock pulses that are generated by the rubber wave generator.…”

Dynamic analysis and structure optimization on trapezoidal wave generator for eliminating the over deviation of the residual wave in shock test measurement

“…Among them, the acceleration-time pulse-based simulation method has been being widely applied for the shock test of various electronic products in industry, of which the waveforms of the specified acceleration-time pulses, as shown in Fig. 1, mainly include half-sine waveform, trapezoidal waveform, and final-peak sawtooth waveform [14], [15]. Among them, the trapezoidal shock pulse can produce a higher response over a wider spectrum than both the half-sine and the final-peak sawtooth shock pulses, and is widely used as the shock test waveform to estimate the reliability of electronic products [16].…”
