sub-impact experimental system elastic-plastic deformation impact force finite elements
A set of experimental system is designed for testing the sub-impact behavior and the systematic dynamical responses in the flexible impact process.The numerical 3-D dynamic finite element simulations show that the experimental system can excite multiple elastic-plastic impacts and effectively simulate the sub-impacts of several typical impact systems.The influence of the materials and the supporting ways of the test beam on the impact process is simulated and the performance index for testing the impact force and beam displacement are determined.
