Abstract

The paper deals with simulation of wheeled vehicle dynamic regimes in laboratory conditions. Based on the analysis of static and dynamic characteristics of the vehicle and test equipment the calculation model was created that calculates the course of a loading moment on the simulator for the given vehicle and driving regime. The basic condition for the simulation is the requirement for reaching congruent courses of driving speeds at the same vehicle control both on the roadway and in the test room.

Highlights

IntroductionWhen designing new solutions within research activities in the field of transportation technology it is impossible to avoid modelling of real systems either in the test room (physical model) or on the computer (mathematical model [1])
When designing new solutions within research activities in the field of transportation technology it is impossible to avoid modelling of real systems either in the test room or on the computer
The simulator role is to induce the same loading on the combustion engine shaft as the loading from the transmission device and run on the real vehicle for the specified regime

Summary

Introduction

When designing new solutions within research activities in the field of transportation technology it is impossible to avoid modelling of real systems either in the test room (physical model) or on the computer (mathematical model [1]) Such a modelling is implemented at creation of control algorithms and programmes for development of computer control systems. The decisive role in the control of drive operation, in cooperation of individual elements as well as the collaboration between the vehicle and driver is performed by automated systems They are able to identify, process and optimize the parameters of vehicle running in the real time. The dynamic driving simulator is a new step in the development of virtual testing of drives It provides researchers, designers and constructors with a deeper insight into the behaviour of a solved drive and offers a direct feedback to their activities from different points of view
