摘　　要：气体流量计量标准装置结构复杂、价格昂贵,在传统实验教学模式下学生难以开展动手操作,为此开发气体流量计量的虚拟仿真实验。运用虚拟仿真技术搭建音速喷嘴气体流量传递标准装置,在虚拟三维场景中学生可对气体流量标准装置的结构和工作原理展开全方位的认知,掌握气体流量量值传递与溯源方法。同时依据检定规程设计气体涡轮流量计检定交互步骤,使学生掌握涡轮流量计的检定流程及其计量性能评价方法。该项目克服了传统流量计量实验教学中存在的难题,取得了较好的实验教学效果,有效提升学生的专业认知和行业从业能力。The gas flow standard device is expensive and has a complex structure,which is difficult for students to operate in traditional experimental teaching.Hence,a virtual simulation experiment project of gas flow metrology is developed.The transmission standard of gas flow capacity of sonic nozzle flow standard is developed based on virtual simulation technology.Through the virtual three-dimensional scene,students can have a comprehensive understanding of the structure and working principle of gas flow devices,and master the quantity transferring and traceability methods of gas flow.Meanwhile,the interactive steps for gas turbine flowmeter calibration are designed based on the verification regulation,which helps students to master the calibration process and measurement performance evaluation methods of turbine flow meter.The difficulties encountered in traditional experimental teaching of flow metrology are well overcome,which achieves good experimental teaching effects.Moreover,the students'major recognition and professional ability are improved effectively by the project.
