摘　　要：重载货运列车缓冲器实验教学存在场地面积大、费用高、周期长、损耗高、风险高、效率低等特点。针对其特点,以HM-1型重载货运列车缓冲器为研究对象,在实验教学项目基础上开发缓冲器虚拟仿真实验教学平台,构建缓冲器结构认知与参数设计、冲击实验设计、缓冲器力学特性优化设计三大学习任务,通过运用界面交互设计引导学生自主完成实验的学习与考核。依托开放式实验教学平台开展实验教学,实现远程在线实验、在线批改,提升实验效率,降低实验成本。The experimental teaching of heavy-haul freight train buffer has the characteristics of large site area,high cost,long cycle,high loss,high risk and low efficiency.In order to solve this problem,taking HM-1 type heavy-haul freight train buffer as the research object,based on the experiment teaching project,the virtual simulation experiment teaching platform of buffer is developed.Three learning tasks,namely buffer structure cognition and parameter design,impact experiment design,and buffer mechanical characteristic optimal design,were constructed.Through the application of interface interaction design,learners were guided to complete the experimental learning and assessment independently.The system relies on the open experiment teaching management platform,realizes the remote online experiment and online correction,improves the experimental efficiency and reduces the experimental cost.
