Exploration on learning-centered experimental teaching of modern engineering measurement technology
Modern engineering measurement technology is an obligatory course for undergraduates ma-joring in engineering in some domestic universities.At present,there are some problems in this course,such as the simple form of experimental objects and the single testing method.In view of the a-bove problems,an exploration on learning-centered experimental teaching is carried out.An annular and an arc wing structure model are designed to replace the original cantilever straight beam wing structure model as the experimental object.On the basis of the original strain measurement,three parts of displacement measurement using laser displacement sensor and Digital Image Correlation(DIC)method and finite element simulation are added.The students showed great curiosity about the new wing structure models,and the new experimental methods and finite element simulation also further en-riched the teaching content of this course.Through these explorations,students can master new testing methods,mobilize their enthusiasm and initiative in class,enhance their ability to solve practical prob-lems with the theory they have learned,and significantly improve the teaching effect and quality.
