面向拆装训练的输油泵机组虚拟维修系统设计
|
摘要
针对输油泵机组实装维修训练存在的不足,设计了面向拆卸与装配训练的输油泵机组虚拟维修系统;通过现有主流虚拟现实仿真平台的对比,选择以Unity3D作为开发平台;分析了系统功能、性能需求,设计了系统多层次模块化训练体系结构;针对系统交互式拆装的核心功能需求,提出一种高效的鼠标拖拽时零部件位置更新算法;为在虚拟训练过程中正确模拟机械零部件拆装的顺序关系,研究了基于事件驱动编程的设计方法;对系统实际运行参数进行测试,满足各项功能、性能需求;系统不仅满足输油泵机组维修训练的需求,还可为其它产品的维修拆装训练系统设计提供参考。
Aiming to overcome the deficiency of petroleum pumping unit real-equipment based training,design the virtual maintenance system for disassemble and assemble training.Through comparison of existing VR simulation platforms,chose Unity 3D as the system develop platform.The functional and performance requirements of the system was analyzed,the multilevel modular framework of system was designed.To realize the system key requirements-interactive disassemble and assemble,the part position update algorithm was proposed.To simulate the parts' assembly and disassembly order in virtual training,the design method based on event-driven was studied.The system practice running parameters meet the functional and performance requirements.It can not only satisfy the demand of petroleum pumping unit maintenance training,but also provide reference for disassemble and assemble training system design of other products.
