Sažetak
Submarine accidents can cause loss of human life and economy, as well as environment damage. Also submarine rescue is difficult for the complexity of rescue process and the uncertainty of the sea state. Success of rescue process is determined by reliability and safety of rescue device. Therefore, research on related device design is rather important. The existing knowledge always supplies some empirical formulas and generates a design scheme by general design rules. The scheme plan obtained may not be a good one due to simplicity of mechanical calculation analysis and particularity of design requirements. To improve design safety and reliability of shipborne device on submarine rescue system, dynamics simulation model of LV-DSRV based on sea state excitation was created in this paper. Wave excitation input at sea state 5 and 8 was considered as the extreme marine working conditions. Kinetic property of LV-DSRV was calculated making use of virtual prototype technology through ADAMS software, and mechanical characteristics of key parts were also analyzed. Optimization strategy was proposed and verified by increasing the number of horizontal wheels and adding gap between horizontal wheels and the track, providing with a case study for similar marine special mechanism design.
