System Design Laboratory

It is the most important to verify the safety of the production design before the real operation. However, the verification which depends on the experience of the production engineer or the rule and regulation cannot be clearly proven or results in overestimation. Therefore, the verification based on dynamic analysis is widely adopted. However, it is impossible for existing programs to support some mechanical equipment such as the equalizer and SPMT (Self-Propelled Modular Transporter). Therefore, this study analyzes the requirements that are essential to simulate the lifting and erection operation in ships and offshore structures and proposes the integrated simulation framework based on multibody dynamics. The proposed framework is composed of five layers such as simulation core layer for solving the equations of motion, interface layer for data communication, simulation components layer including constraints, forces and collision, equipment layer, and service layer. This study develops a dedicated and differentiated program for dynamic analysis in ships and offshore structures, named SyMAP (SyDLab’s Multibody Analysis Program).
