Abstract
ENGLISH ABSTRACT: The construction and functioning of the hydraulic driven towing trolly at the Department of Mechanical Engineering at the University of Stellenbosch is discussed in detail after which the equivalent non-linear mathematical model is derived from basic principles. It is evident from the theoretical study that the trolly has a first order open loop structure, while the total closed loop system is a second order system.
AFRIKAANSE OPSOMMING: Die konstruksie en werking van die hidroulies aangedrewe sleeptrollie by die Departement van Meganiese Ingenieurswese aan die Universiteit van Stellenbosch is bespreek, waarna die ekwivalente nie-lineêre wiskundige model daarvan vanuit grondbeginsels afgelei is. Dit blyk uit die teoretiese ondersoek dat die sleeptrollie 'n eerste-orde ooplusstruktuur het, terwyl die totale geslotestelsel 'n tweede-orde-sisteem is.
