多次弹塑性撞击实验系统的设计与数值仿真
Design and Numerical Simulation of Experimental System for Multiple Elastic-plastic Impacts
摘要
Abstract
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.关键词
