摘要
为了精确构建复杂机械设备数字孪生模型,提出了一种针对多异构并联机构组合体的数字孪生方法。设计了面向特殊机电产品的多异构并联机构组合体数字孪生系统,对该机电产品的多异构并联机构组合体进行运动仿真。搭建了数字孪生虚拟实体,设计了相应的多异构并联机构组合体运动学位姿求解算法;通过信息物理系统(CPS)连接虚拟实体与物理实体,实现了虚拟实体与物理实体的运动关系映射,虚拟实体的运动与物理实体保持同步。仿真和实际运行表明,算法效率满足实时运行需要,多异构并联机构组合体数字孪生系统满足数字孪生高同步性要求。
The digital twinning system of multi-heterogeneous parallel mechanism combination for special mechanical and electrical products is designed,and the motion simulation of multi-heterogeneous parallel mechanism combination for a mechanical and electrical product is carried out.The digital twin virtual entity was built,and the corresponding motion degree attitude solving algorithm of multi-heterogeneous parallel mechanism combination was designed.The virtual entity and physical entity are connected through cyber-physical systems(CPS) to realize the mapping of the motion relationship between the virtual entity and the physical entity,and the motion of the virtual entity is synchronized with the physical entity.Simulation and actual operation show that the algorithm efficiency meets the needs of real-time operation,and the digital twinning system of multi-heterogeneous parallel mechanism combination meets the requirements of high synergy of digital twin.
