Modeling and performance analysis of a pneumatic steering system to enhance maneuverability in T-55 Armored Vehicles

This study presents the development and analysis of a pneumatic steering mechanism for the T-55 tank, addressing challenges inherent in traditional manual systems. These systems require excessive physical effort due to high resistance in linkages, leading to operator fatigue and reduced maneuverability. The proposed mechanism integrates a pneumatic cylinder and “rocker arm to convert linear motion into precise rotational control, enhancing steering performance and driver comfort. The design leverages compressed air as a lightweight, safe, and responsive medium, ensuring adaptability to diverse operational conditions. Structural analysis via finite element methods (FEA) confirmed the mechanism’s durability, with the rocker arm exhibiting a maximum von Mises stress of 46 MPa, well below the material’s yield strength of 200 MPa. Fatigue analysis further demonstrated the mechanism’s capacity to endure over one million load cycles, ensuring long-term reliability. Dynamic simulations using MSC.ADAMS validated the system’s performance. The piston stroke, ranging from 0 to 150 mm, allowed precise control of steering linkages. Motion analysis confirmed a free travel distance of 132.5 mm, aligning with practical requirements for T-55 steering systems. The pneumatic system also reduced operator effort by over 50% compared to manual systems, significantly improving operational efficiency. Compared to traditional systems, the pneumatic mechanism enhances maneuverability, enabling smooth directional changes in challenging terrains while reducing driver strain. Its modular design facilitates seamless integration with existing tank frameworks, minimizing modifications. This work demonstrates the potential of pneumatic systems to modernize tracked vehicle steering mechanisms, providing enhanced agility, reliability, and safety. The findings ensure that tanks like the T-55 remain highly effective in modern combat scenarios.
