Research on wheeled armoured fighting vehicle in curvilinear motion

The paper shall present results of simulation research studies performed using a simulation model of a vehicle in which ABS and EBS system were taken into consideration as well as hydropneumatic suspension. A decision was made to conduct the simulation studies following three tests: circumferential fixed motion; emergency braking in curvilinear motion; stepping extortion on the steering wheel. As a result of performed simulation studies, more than 30 physical quantities were recorded describing the curvilinear motion of the AFV vehicle. The following were selected for presentation in listings: motion trajectory; progress of the value of lateral and side acceleration of the vehicle centre of inertia; progress of circumferential velocity values of driving wheels (essential at braking); progress of the vehicle velocity values recorded in the vehicle's centre of inertia and in places corresponding to positions of driving wheels; and progress of the values of vertical reaction forces under the driving wheels. Catalogue of the parameters being changed for the simulation is looked up to real objects and trends occurring in the changes being introduced. Paper presents progress of the value ofverticalforce in different conditions and vehicle motion trajectory. It also shows general diagram of hydropneumatic suspension system in view of the vehicle and diagram of hydropneumatic suspension system.
