    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 are developed. The testing device can be used to conduct the material experiments of tribology characteristics for bearings, gears, seals in aero-engines. The combination of virtuality simulations and reality operations is helpful for students to promote the understanding of the knowledge of basic theory, operating steps, experimental processes, results presentations of high-speed and high-temperature friction and wear testing, and students can receive practical training without the restrictions of time and space. After completing the virtual simulation experiment, offline physical operation training is carried out. In this way, students can form a realistic understanding of the structural composition and operation process of the high-speed and high-temperature friction and wear testing device. Finally, the study performance of different learners are evaluated based on virtuality simulations, reality operations, and experiment reports by the ways of process assessment and outcome assessment.
