Today, access control and security systems are widely implemented, ranging from entry-exit points to shopping centers, business complexes, enterprises, universities, border checkpoints, and other facilities. These systems use a wide variety of equipment, including different types of turnstiles, bollards, and blockers. Such equipment can be used both in stationary conditions and as mobile units. The type of control integrated into these systems depends on the specific control requirements. For standard access control systems, operation can be managed via mechatronic controls with various sensors. However, for systems responsible for security, the equipment must primarily feature high anti-ram resistance. This includes a robust external structure and an internal control system that ensures rapid response and sustained positioning of the "blocking" device. This functionality is achieved through the use of hydraulic drives. On the market, such access control systems must remain competitive by offering precise operation, quick response times, safe usage, easy maintenance, and durable performance. This study examines hydraulic control systems and presents the design of a bollard system. The study includes the modeling of wall displacement in the accumulator housing under varying pressures within the hydraulic system. The objective of the research was to select an accumulator with higher pressure capabilities, model its operation, and enable the use of a lower-power electric motor. This, in turn, reduces the cost of the system while increasing the operational lifespan of the electric motor and pump, as the required power is provided by the hydraulic accumulator.
