加强板型钢桥防护装置耐撞性能研究

摘要

In this paper,ANSYS/LS-DYNA which is a non-linear dynamics finite element software is applied to simulate the crashworthiness performance of the two stiffened plates,and the crashworthiness performance factors of the two stiffened plates were analyzed and compared to optimize two stiffened plates.Ultimately with two kinds of stiffened plates to replace some components of the traditional box-type protective devices aimed at improving the overall crashworthiness performance of protective devices.%借助ANSYS/LS-DYNA非线性有限元软件模拟两种加强板的耐撞性能,并对影响两种加强板耐撞性能的参数进行了分析比较,优化加强板的耐撞性能,最终用两种加强板替换传统钢质箱式防护装置的部分构件,旨在改善防护装置整体的耐撞性能.
