Smallwood algorithm
WebTo eliminate DC offset, the mean of the first 100 points at the beginning was subtracted from the whole acceleration data. 19 Each SRS of the two cases was obtained using the Smallwood algorithm ... WebJun 25, 2014 · A base input time history was synthesized as an initial step. Response time histories were then calculated via the Smallwood algorithm for a number of amplification factors and natural frequencies. This method is adequate but inefficient. Furthermore, an SRS does not have a unique time history.

WebSmallwood algorithm (although exact solution could be obtained via Laplace transforms). vibrationdata gt Select Signal Analysis gt SDOF Response to Base Input This example is resonant excitation because base excitation and natural frequencies are the same! 29 Sine Vibration Exercise 4 Vibrationdata File channel.txt is an acceleration time history Webanalysis procedure be used. The Smallwood algorithm is the obvious choice. Before the time history is passed to the SRS processor, any low-frequency offsets must be removed. This operation, called preprocessing, is done in two steps: 1. A block of data just before the shock is averaged and the result is subtracted from the whole time history. 2.
