摘要：为了解决三维空间中的非线性动力学问题,本文提出了一种新的等几何实体单元,并通过张量分析中的坐标变换得到其非线性应变场.为了使所提出的单元能够无缝地应用于计算机辅助设计(CAD)和计算机辅助工程(CAE)系统中,采用三变量T样条作为等几何实体单元的基函数.借助Bézier投影法,提出了基于T样条的等几何实体单元的局部网格更新算法.在重要区域对网格进行局部细化以获得准确的结果,在重要区域以外对冗余单元进行粗化以提高计算效率.因此,非线性动力学分析中的计算效率和计算精度得到了平衡.三个静力学数值算例验证单元弹性模型的正确性.通过柔性摆仿真算例研究该单元的动力学特性.通过实验测试该单元解决非线性动力学实际问题的能力.应用局部网格更新算法进行柔性摆与障碍物碰撞接触的仿真.通过对计算结果和计算耗时的分析,研究基于局部变网格T样条的实体单元在非线性动力学问题中的有效性.
