The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

Impulsinių apkrovų veikiamos netiesinės dinaminės sistemos "Neįgalus žmogus - vežimėlis - transporto priemonė" judesio stabilumo tyrimas / Motion stability analysis of the nonlinear dynamic system "Man - Wheelchair - Vehicle" under action of impulsive loadsGriškevičius, Julius 02 November 2005 (has links)
Nowadays disabled persons are actively integrated into social life and different compensatory equipment allows them to work and travel independently. The wheelchair is one of such means; it provides mobility function for physically impaired persons. Not every disabled person has possibilities to travel by his own car, it is more convenient to use public transport facilities. Wheelchair users' transportation safety is one of the most important problems facing transit providers and engineers. Improperly or totally unsecured wheelchair can lose the stability and tip over during the emergency driving situations and result in passenger falling and becoming injured. The main object of the scientific research work is complex dynamic system "Man - Wheelchair - Vehicle", which is under action of environmental factors (road roughness, motion oscillations of vehicle). The main tasks of the work are to form and research non-linear model of dynamic system considered, to define system's stability limits and to provide means for save travel. Also to determine main characteristics of the external action and analyze its influence on to considered system; to build engineering computation methodology for estimation of the rational parameters to fasten the wheelchair to the vehicle.
