Impulsinių apkrovų veikiamos netiesinės dinaminės sistemos

Abstract

Nowadays disabled persons are actively integrated into social life. Different compensatory equipment allows them to work and travel independently and one of such means is the wheelchair. Not every disabled person has possibilities to travel by his own car, it is more convenient to use public transport facilities. Transportation safety of the wheelchair users is one of the most important problems facing engineers and transit providers, becouse improperly or totally unsecured wheelchair can lose the stability and tip over during the emergency driving situations. The main object of the scientific research work is complex dynamic system "Man - Wheelchair - Vehicle", whis is under action of environmental factors (road roughness, motion oscillations of vehicle). The main tasks of the work are to form and research nonlinear model of dynamic system considered and to define system's stability limits, providing means for safe travel; to determine main characteristics of the external action and analyze its influence on to dynamic system; to build engineering computation methodology for estimation of the rational parameters to fasten the wheelchair to the vehicle.
