Mathematical model for engineering tracked vehicle suspension system connections influence assessment

Abstract

Abstract This paper is devoted to designing imitational mathematical model that can help in tracked vehicle, which has connected suspension system, motion smoothness research. In this paper advantages and disadvantages of existing mathematical models are analyzed which allow to evaluate different design choices expediency at designing stage. In order to take suspension system connections into consideration and evaluate the possibility of using the created mathematical model to study transport vehicle motion smoothness the existing rectilinear motion mathematical model, created by BMSTU scientists, was modified. Modeling was carried out in MATLAB Simulink program complex. The results of connected suspension system imitational mathematical model usage are demonstrated on solving the following problem: tracked vehicle motion smoothness comparison in case of using connected and independent suspension system. These results show that connections in suspension system, which were added to decrease chassis loads, do not influence the tracked vehicle motion smoothness in any way. Thus, the modified imitational mathematical model can be used for tracked vehicle, which has connected suspension system, motion smoothness research.
