有限元软件LS-DYNA在柔体仿真中的应用

LS-DYNA Application in Flexible Structure Simulation

对工程中广泛应用的柔性网系统进行仿真研究是计算机仿真领域的难点之一。通过LS-DYNA对警用网枪发射的柔性网体进行建模和动力学仿真,介绍了其在非线性的柔体仿真中的应用。仿真与实验结果相吻合。说明了有限元法在柔性体仿真中的有效性和重要价值。

Flexible net structure is widely used in engineering. It is an extremely difficult problem in computer simulation field that simulation study on the flexible structure. LS-DYNA was used to modeling and dynamics simulation, and to introduce its application in nonlinear flexible structure simulation. The simulation results are consistent with the data collected in an experiment. It shows that FEM is an efficient and important method in flexible structure simulation.
