The paper shall present the way for building a model for simulation studies of the wheeled armoured fighting vehicle with hydropneumatic suspension of driving wheels axles. Thus developed model shall be used to conduct simulation studies in the area of the vehicle safety. The scope of terms and conditions for applications of hydropneumatic suspensions in wheeled armoured fighting vehicles is justifled due to a number of their advantages, such as: progressive characteristics of elasticity provides great driving comfort with a small load, as well as apossibility of placing a considerable load on the vehicle (the requirements are mutually exclusive in classical suspension). Compressed nitrogen, sealed in the sphere using an elastic diaphragm, is approximately six-fold more flexible than steel springs elements at static load of the suspension, which provides high level of driving comfort; apossibility to lower the height of the vehicle by changing the road clearance which effects in e.g. higher availability for airborne transport and soon. However, they are not free from disadvantages; therefore, it is the studies of their justified use, especially related to traffic safety, that should have a final say in individual cases. The here to presented model of hydropneumatic suspension and the vehicle motion model are applied to assess dynamic capabilities and evaluate the real object motion safety.
