Multidisciplinary Design Optimization for Heavy Machinery Based on HLA

To achieve the global optimal of heavy machinery and other complex production, a computation environment of collaborative optimization for multidisciplinary design based on high level architecture (HLA) was constructed. According to the interface specification of HLA, the coupled state variables were mapped to corresponding published or subscribed attributes of an object class. So that the collaboration and interoperation between the disciplines were implemented. As a result, the global optimal of complex production was achieved based on the synergistic effect owing to the interoperation between the disciplines. Application of proposed optimization model in designing the schnabel car could not only take off the deadweight, but also improve its running stability.
