The purpose of this research is to develop a virtual functional evaluation system for designing automatic machinery where multi-disciplinary simulators for workpiece deformation, machine kinematics and control software can be coordinated and collaborated each other, and where the realistic behavior of the machine can be simulated.The results of the research were summarized as follows :(1)A methodology and a developing environment were proposed where commercial off-the-shelf kinematic simulator and control software simulator could be communicated real-time using RTI middleware compatible with the distributed simulation standard HLA. The environment was applied to verify the dynamic behavior of a CD drive mechanism under control, and it was confirmed that several kinds of hidden mechanical and control design mistakes could be easily found by using this environment.(2)To realize the efficient simulation time advancement in the collaborative simulation among different simulators, the Time Warp mechanism was developed where the time step could vary in each federate. This mechanism was implemented in federates of the collaborative simulation, and it was confirmed that the simulation efficiency of the automatic machinery controlled by the FieldBus was greatly improved.(3)To predict the workpiece deformation by FEA for verifying the automatic packaging machine, a multi-resolution FEA mesh generation method was developed where the number of elements and geometric qualities of the elements can be controlled flexibly. And a deformation simulation algorithm of thin packaging film based on discrete shell model was implemented, and the defects of the packaging process caused by the fine creases could be predicted to some extent.

本研究的目的是开发一个用于设计自动化机械的虚拟功能评估系统，其中工件变形、机器运动学和控制软件的多学科模拟器可以相互协调和协作，并且可以模拟机器的真实行为。研究结果总结如下：（1）提出了商业现成的运动学模拟器和控制的方法和开发环境 软件模拟器可以使用与分布式仿真标准HLA兼容的RTI中间件进行实时通信。该环境用于验证受控CD驱动机构的动态行为，并证实使用该环境可以轻松发现多种隐藏的机械和控制设计错误。(2)为了实现不同模拟器之间协同仿真中的高效仿真时间推进，开发了时间扭曲机制，其中时间步长可以在每个联邦中变化。该机制在协作仿真联盟中得到应用，证实现场总线控制的自动化机械的仿真效率得到了极大的提高。(3)为了通过有限元分析预测工件变形以验证自动包装机，提出了一种可以灵活控制单元数量和单元几何质量的多分辨率有限元分析网格生成方法。并实现了基于离散壳模型的薄型包装薄膜变形模拟算法，可以在一定程度上预测因细小折痕而引起的包装过程缺陷。
