Abstract

The article is devoted to the research and generalization of the principles of development of the software dynamic model of autotractor internal combustion engines (ICE). The engine dynamics model is structured and the criteria for model identification with the object are defined. The formal description of the expert object (EO) includes a functional diagram of the internal combustion engine that characterizes its parameters and operators that establish the appropriate relationships between these parameters. The dynamic model is based on the known ICE equations at the moments. Differential equations of velocity and acceleration of the crankshaft in static and dynamic modes were used for modeling. Transient characteristics, amplitude-frequency and energy spectra are determined. An example of modeling transients using the Simulink Matlab package in case of problems in individual cylinders is considered.
