Dasy Based Tool for The Design of Ice Mechanisms

Abstract: Shrnutí Článek prezentuje nastroj pro navrhovani novych mechanismů spalovaciho motoru založeny na znalostni databazi DASY. Z mechanismů motoru byl vybran rozvodovy mechanismus OHC na kterem byl nastroj vyvinut a testovan. Nastroj obsahuje kinematicky a dynamicky model rozvodu napojeny na klikovy mechanismus. Podrobnou kalibraci a naslednou validaci třech dynamickych modelů s měřenymi daty, byly ziskany hodnoty neznamych parametrů modelů, ktere jsou zaznamenany v DASY a mnohe parametry jsou přimo použiteln… Show more

“…The process and evaluation of the calibration is identical as in the case of [3]. For the evaluation of the objective function, the genetic algorithm searched for the minimum value of the sum of the squares of the deviations between the objective function and the current curve from the simulation at the reference points.…”
