Abstract

A new concept for ensuring the roll stability of special armored vehicles (SAVs) is proposed, along with a mathematical model for calculating stabilization conditions of a V-shaped blast-resistant body mounted on an SAV chassis. The performance of various specialized missions by SAVs requires the development of an actuator and mechanism to stabilize the vehicle body during complex maneuvers, especially when the inertial forces negatively affect roll stability. The article presents an advanced technology for monitoring roll stability and stabilizing the SAV body using a specially designed linear force actuator. This technology significantly increases the roll stability of the SAV, improves driving dynamics, smooths vehicle motion, and reduces vibrations, jolts, impacts, and body roll during movement. As a result, vehicle control becomes easier, onboard weapon systems (particularly operator-controlled combat modules) can be used more effectively, and the transport of personnel, wounded soldiers, or patients becomes safer and more comfortable. Additionally, enhanced roll stability improves SAV off-road mobility, especially when traversing difficult terrain—an essential feature in combat environments. The proposed mathematical model of body stabilization can also be applied to truck and passenger car bodies, contributing to the advancement and modernization of vehicle structures in both domestic and international automotive engineering. The developed kinematic and layout schemes of the anti-roll mechanism, along with the mathematical model of the actuator and stabilization mechanism, ensure the technological feasibility and operational applicability of the system in real combat conditions.

Keywords: military vehicle, special armored vehicle, roll stability, rollover, mathematical model, static stability coefficient, calculation methodology, linear force actuator, stabilization system, stabilizing actuator
