Substation of methods for conducting computational studies of highspeed tracked vehicles

Abstract

This article describes a modern approach to studying the dynamic characteristics of highspeed tracked vehicles. A large number of domestic and foreign specialists from various branches of mechanical engineering have studied the issues of modeling various systems and individual units of tracked vehicles. Through the use of calculation and simulation models, engineers have the opportunity to study the characteristics of the designed product with high accuracy before the stage of its manufacture. Models built in modern software packages are saturated with mathematical apparatus. To fully realize the potential of such packages, not only a deep study of their algorithms and operating methods is required, but also the equations from which the models are composed. The purpose of this article was to study the mathematical apparatus of the software package, in which a one-dimensional calculation and simulation model of a high-speed tracked vehicle which was previously implemented, to find its dynamic characteristics. The differential algebraic equations, ordinary differential equations and differential equations with partial derivatives, methods and problems related to their solution (the presence of discontinuities) considered in the article allow the engineer to better understand the algorithms of the functioning of simulation modeling software packages. As a result, in the future this makes it possible to create higher-quality calculation and simulation models, which at the earliest stages of design will allow predicting the behavior of the systems and complexes being developed more accurately. In the future, a more in-depth study of the equations and methods presented in the article is planned, as well as determining the most optimal of them for obtaining the necessary results with minimal time and computer resources and with high accuracy.
