Abstract:

In the R&D of complex products, different design stages have different design goals and different simulation tasks, which need different resolution complex products simulation models. The models and interfaces for the multi-resolution characteristics are defined and thus the resolution control mechanism is studied. The description mechanisms for the system structure status and model resolution state are established separately, the control mechanism for the system resolution is proposed, and a cross level switching technology is sorted out. The experimental results show that the method can effectively solve the problem of model resolution switching, which ensures the simulation accuracy, improves the simulation efficiency and saves the required simulation resources. The method has simple structure, and can be popularized in the future.

Key words: complex products, multi-resolution, model resolution, control mechanism, switching technology
