ANALYSIS OF TIME DEPENDENT TRANSIENT PHENOMENA OF NONLINEAR COUPLED SWINGING SYSTEMS OF VARIABLE STRUCTURE AND CONDITIONAL CONNECTIONS

A train consists of spring-connected masses vibrating under the action of external forces variable with time. In adverse cases, very great forces arising in the draw gear may tear the train. This paper examines a train formed by cars with continuous draw bar. The train consists of a locomotive of mass M sub o and of cars of masses M sub i. Forces between cars are transferred by draw and buffer gears. Buffer and draw gear of the locomotive can be modeled by a spring of nonlinear characteristics, and with it a damper in parallel of nonlinear characteristics, directly connected with mass M sub o. Buffer gears of the cars are similar to those of the locomotive, but the draw gears are connected with mass M sub i via a continuous draw bar of mass M sub i and an undamped draw spring K sub i. Force transfer between adjacent vehicles is achieved through conditional connections: the continuous draw bar cannot transmit compressive forces, and the buffer spring cannot transmit tension. Thus, the structure of the system varies with time, depending on the connections between the adjacent vehicles.
