摘要
在现在的分析，在数字模拟使用的几个参数在综合研究被调查在这模拟的进程和结果上获得他们的影响。学习的参数是元素明确的表达，磨擦系数，和材料模型。用非线性的有限元素方法的数字模拟被进行为几种碰撞情形生产虚拟试验性的数据。当真实试验性的数据，和这些被用来验证方法，碰撞在一个真实事故案例中引起的模式和尺寸损坏被假定。执行的元素模型学习显示 Belytschko-Tsay 元素明确的表达应该在虚拟实验为使用被推荐。为包含的材料的磨擦系数的真实价值在模拟被使用，这被推荐。为材料模型的学习，有高收益力量的材料的申请在方面壳结构为使用被推荐。
In the present analysis, several parameters used in a numerical simulation are investigated in an integrated study to obtain their influence on the process and results of this simulation. The parameters studied are element formulation, friction coefficient, and material model. Numerical simulations using the non-linear finite element method are conducted to produce virtual experimental data for several collision scenarios. Pattern and size damages caused by collision in a real accident case are assumed as real experimental data, and these are used to validate the method. The element model study performed indicates that the Belytschko-Tsay element formulation should be recommended for use in virtual experiments. It is recommended that the real value of the friction coefficient for materials involved is applied in simulations. For the study of the material model, the application of materials with high yield strength is recommended for use in the side hull structure.
