Abstract:Prispevek opisuje postopek optimalnega projektiranja okvira terenskega tovornega vozila. Namen raziskave je minimizirati težo sedanjega okvira. Pri tem zahtevamo, da mora togost okvira ostati približno enaka, medtem ko lahko parametre prerezov spreminjamo znotraj predpisanih mej z namenom, da bi zmanjšali težo. Upoštevali smo več ločenih obremenitvenih primerov, ki simulirajo različne situacije obremenjevanja okvira. Optimizacijsko nalogo smo formulirali v obliki standardnega problema matematičnega programiranja. Ta problem smo nato rešili z uporabo gradientne optimizacijske metode. Okvir vozila smo diskretizirali z uporabo zelo natančnih končnih elementov nosilcev.

Title:Optimum frame for an off-road truck
Abstract:We present an approach for the optimum design of a frame for an off- road truck. The objective was to minimize the weight of an existing frame. The stiffness of the frame had to remain approximately the same, while the cross-sectional parameters could be varied in some specified range in order to minimize the weight. Multiple load cases were taken into account simultaneosly in order to consider different loading situations. The design problem was formulated in the form of a standard problem of mathematical programming. This problem was then solved using a gradient-based approximation method. The frame of the truck was discretized by employing highly accurate beam finite elements.
Keywords:off-road vehicles, vehicle frames, construction optimization, load cases
