Konceptlösning nödbogseringssystem till bärgarbandvagn 90 (BGBV90)

Sammanfattning

BAE Systems Hägglunds in Örnsköldsvik develops and manufactures military vehicles, including the recovery vehicle 90 (BGBV90). This thesis investigates the feasibility of implementing an emergency recovery system on the BGBV90, aiming to enable the coupling and towing of combat vehicles without personnel having to leave their vehicle. Current manual coupling methods pose safety risks in operational environments, making this solution relevant. The work began with the development of two concepts, which were then evaluated and compared using design reviews and decision matrices. The selected concept was further developed and optimized with a focus on mechanical design, control systems, and compliance with specified requirements. To ensure strength and functionality, finite element analyses (FEM) were conducted. Additionally, a site visit to the Norrbotten Regiment, I 19 and a market analysis were included to incorporate experience from existing recovery solutions. Integration aspects such as camera surveillance and remote operation were studied to improve the system’s user-friendliness and safety. The results show that the developed concept meets the project requirements for functionality, safety, and usability, featuring an electric winch and mechanical tow hook enabling remote coupling. FEM analyses indicate that the design withstands the specified loads. Proposals for field testing and further development have been identified to verify the system’s robustness in practical use. The solution is expected to contribute to increased personnel safety and improved operational capability during recovery operations.
