On HLA-Based Collaborative Simulation Techniques

The design and development of a complex system as well as the simulation of its dynamic behavior are usually involved in multidisciplinary field knowledge. HLA-based collaborative simulation is an effective way to integrate different disciplinary models together in distributed environments. In this paper, the HLA adaptor is adopted to realize model transformation so that models created through commercial software are compatible with HLA. Moreover, in order to solve the difficulty of wrapping ABAQUS software, an ABAQUS engine encapsulation technique is proposed. It is helpful for developing HLA adaptor corresponding to ABAQUS software, and can facilitate the integration of ABAQUS models with HLA-based collaborative simulation platform. Next, a time-advance algorithm based on time-stepped is described, which is the main time-advance way in complex system simulation. Finally, a prototype system is developed to demonstrate the high fidelity of collaborative simulation and the effectiveness of our simulation platform.
