SIMULATION OF TRANSITIONAL PROCESSES OF DYNAMIC MODEL OF POWER ENERGY INSTALLATION OF MACHINES FOR FORESTRY WORKS

Abstract

The article is devoted to the study and generalization of the principles of software development dynamic model of automotive tractor engines internal combustion engines (ICE). The structured model engine dynamics and defined criteria for identifying model with the object. Formal description of the expert object (EO) includes a functional diagram of the internal combustion engine that characterizes its parameters and operators that establishing the appropriate relationship between these parameters. The dynamic model is based on the known ICE equations in moments. For modeling were used differential equations of speed and acceleration of the crankshaft in static and dynamic modes. The transient characteristics, amplitude-frequency and energy spectra are determined. An example of modeling transient processes using the Simulink package Matlab package in the event of malfunctions in individual cylinders.
