Abstract: The dynamic mechanical properties of honeycomb beams under impact load are measured by using the independently developed drop-weight impact test system. Combined with graduate scientific research experiment, independent inquiry scientific research experiment teaching project is set up to make students understand the difference between dynamic mechanical properties and static mechanical properties of honeycomb beams, and more the difference between elastic response and plastic response under impact load. In the process of using instrument to carry out the test, the students will deepen the understanding of the abstract theory in structural mechanics and improve the ability to integrate theory with practice. The classroom teaching content is richer by materializing the abstract theory in structural mechanics, it has exercised students′ practical ability and scientific research literacy, and stimulated students′ exploration spirit of deeper knowledge.
