Experimental Design of Friction and Wear under the High-Speed and High-Temperature Conditions Based on the Combinations of Virtuality and Reality

  • 摘要: 航空发动机机械基础零部件材料的高速高温摩擦磨损测试具有实验周期长、实验过程复杂、安全风险多等特点,为了降低学习者使用实物测试装置时的风险因素、实验周期与教学成本,设计了一种用于航空发动机中轴承、齿轮、密封等关键机械基础零部件材料的高速高温摩擦磨损测试装置,以及与此实物装置高度一致的虚拟仿真实验系统。通过虚拟仿真实验和实物操作训练相结合的方式,辅助熟悉掌握高速高温摩擦磨损测试的基础知识、操作步骤、实验过程、结果展示等,并实现不受时空条件限制、实验设备限制的实践训练。在完成虚拟仿真实验后再开展线下实物操作训练,让学习者对高速高温摩擦磨损测试装置的结构组成和操作流程形成实感认知,教师则对学生的虚拟仿真实验、实际操作实验、最终实验报告等分别进行过程性和结果性综合评价,以提升摩擦磨损的测试效率和实践效果。

     

    Abstract: The material test of friction and wear under the high-speed and high-temperature conditions has some difficulties, such as long experimental period, high experimental complexity and security risks. In order to lower the risks, periods, and costs during operating, the testing device and corresponding virtual simulation system were developed. The testing device can be used to conduct the material experiments of tribology characteristics for bearings, gears, seals in aero-engines. The combinations of virtuality simulations and reality operations are helpful to promote the understand the knowledge of basic theory, operating steps, experimental processes, results presentations, etc. The exercises of high-speed and high-temperature tests can be carried out without the restrictions of time and space, and many students can conduct the tests of virtuality simulations at the same time. Then the offline actual operations were carried out after virtuality simulations, which can improve the realsenses of mechanical structure and operating process of the tribometer for the learners. The study performance of different learners were evaluated based on virtuality simulations, reality operations, and experiment reports by the ways of process assessment and outcome assessment.
