INVESTIGATION OF THE CABIN ACCELERATION PROCESS FOR THREE GROUPS OF ELEVATORS UNDER ENGINE ACCELERATION
Nikolay Hristov With this article, preparations have been made for a multi-criteria study, by collecting information on a series of passenger, cargo and hospital winches under natural mechanical characteristics of the engine acceleration. A methodology with a Runge-Kutta algorithm has been introduced, based on which the system of differential equations describing the movement of the elevators in the acceleration process will be solved. After the determination of the design parameters for the considered winches, the change in speed, the displacement of the cabin in the process of acceleration, as well as the change in the acceleration time and the engine torque are determined. The ultimate goal of the study is to accumulate experience and a sufficient database from which to derive regression models with the possibility of applying the author`s DEFMOT approach in the field of mechanics.
