摘　　要：在复杂产品研发设计过程中,不同设计阶段有不同的设计目标,并依据仿真目标有不同类型的仿真任务,需要不同分辨率的复杂产品仿真模型参与仿真。针对多分辨率特性对模型与接口进行定义,在此基础上研究模型分辨率的控制机制,对系统结构状态和模型分辨率状态分别建立描述机制,提出系统分辨率的控制机制,梳理出一种跨层次切换技术。经过实验验证,该方法可有效解决模型分辨率切换问题,在保证仿真精度的同时,提升仿真效率,节省所需的仿真资源。该方法结构简单,有望在未来进一步推广使用。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.
