Dynamic tests of vehicles equipped with run-flat wheels

Abstract

The article also tackles topics related to dynamic testing of vehicles equipped with massive wheel inserts. The subject matter was taken due to the modernization of the Polish Armed Forces. The majority of vehicles obtained for the army are equipped with wheels with massive inserts. With the introduction of this solution to the army, there was a need to check the correctness of the operation of wheels with massive inserts. The Military Vehicles Research Laboratory of the Institute of Armoured and Automotive Technology developed a research method, which the authors presented in the following article. Dynamic testing is carried out in a practical way by unsealing the tire. The results of dynamic tests carried out on a selected military special vehicle equipped with wheels with massive inserts, which allow the vehicle to move after the tire is unsealed, were also presented. This condition can be caused by various situations, such as: passing the vehicle through the spike strip or the shooting through the tire. Special vehicles, both military and police, are highly vulnerable to the above events and must be able to evacuate from the place of danger even in the case of an unsealed tire.
