Abstract

The results of investigating the influence of the time constant of acceleration signal transformation or vibration speed into a displacement signal are given. Regularities of displacement signal amplitude change after transformation of acceleration and speed signals have been determined. It is shown that the error of displacement signal amplitude change depends on the transformation time constant for the intended frequency of the input signal. Thus, its minimum value corresponds to the value of the transformation time constant, equal to half an input signal period. The results of displacement measurements obtained by using vibration speed sensors and the results of their comparison with data, obtained by employing the displacement master sensor, are given.

Šiame tyrime keleivių srauto dinamikos palyginimui buvo pasirinktas Tarptautinis Krokuvos aerouostas ir trys Baltijos šalių oro uostai. Per paskutiniuosius trejus metus (2004–2006) daugiausia keleivių buvo aptarnauta Tarptautiniame Rygos oro uoste – 5 433 461 keleivis; Tarptautiniame Krokuvos oro uoste – 4 416 896 keleiviai. Talino oro uostas aptarnavo 3 940 366 keleivius ir galiausiai Tarptautiniame Vilniaus oro uoste buvo aptarnautas 3 727 501 keleivis. Taip pat straipsnyje analizuojamos keleivių ir lėktuvų srauto Tarptautiniame Vilniaus oro uoste gerinimo galimybės.
