Özet
SUMMARY Traction System is a group of elements that realizes the aim of transporting a certain mass in a certain maner, for a certain distance. In this work“Electric. Railway Traction Systems”will be prefered among several systems. Energy tra nsfer of transient response in stimulation equipments will be analyzed for this system. Electrical railway traction system is developed in some steps» To analyze energy transfer of transient response in stimulation equipments?“Trolley Stimulation”system will be used. This system can be analyzed by dividing it into three sub-systems. (1) Electric motors (S)Train of Sear's» (3) Wheel and Axle» Then by combining these sub-systems» a mathematical model of the whole system'can be^'deVi'ved. An electro-mechanic system that has electrical and mechenical elements can be transformed into an electric circuit by using“Analogy”and“Duality”. For this circuit j state variables method is used to find the whole solution which involves the forced and natu ral solutions. Stimulation equipment must be able to overcome the inte rior and exterior destructive effects» Calculation of inter i or energy need of the stimulation equipments can be done by means of mathematical model expressed in previous paragraph Analysis and the effectts of exterior energy need on stimula tion equipment will be discussed under a different topic. Ho rizontal and vertical motion of the body of a vehicle causes destructive effects. Because of these motions several resis tances appear like it) Rolling resistance between rail and w~ heelü (S) inclination resistance (3) acceleration and decele ration resistances (4) wind resistance proportional to square of velocity. Analysis of the effects of these resistances on wheels is very important to understand the system. The sum of resistance forces that appear in and out of stimulation equipments and effects of destructive torgue forms the load torque. By transforming load torque into a viscous friction element? the basic relation between load "torque and motor torque can be derived. With the help of this relation, transient response of N(s> output dependent ^on U(s) input is relaized. Therefore* all steps of trans- fering input energy to load element is investigatable. The aim of the analysis and calculation as explained above is to derive the electric and electronic models which are the parts of stimulation system. The experiments about these mo dels will give some knowledge and characteristic about the e~ lectro-mechanical system.
