平板螺旋线圈参数对其共振频率的影响
... 技术 ,自从这项技术在2007年被报道以来,一直吸引很多学术界的注意力。在本篇论文中,主要分析了一个基于WiTricity原型的平面螺旋结构,在无线电能传输系统中,要得到线圈的共振频率至关重要,因此,本论文分别用公式法和三维有限元法(FEM)的涡流磁场阻抗矩阵计算了其共振频率,模拟了其等效电路。结果表明后者有更好的精度。为了减少共振频率,分析了不同条件下定量研究之间的关系参数和副调制的原型的共振频率。研究结果发现提供了一个坚实的基础优化WiTricity技术的原型 ...

Fast Corotated FEM using Operator Splitting
在本文中,我们提出了一种新的算子分裂方法的共形有限元模拟。共线性材料模型的变形能由两个附加项组成。第一项模型在各个空间方向上拉伸,而第二项描述体积变化的阻力。通过将反向欧拉时间积分格式表示为一个优化问题,我们证明了第一项对旋转是不变的。这允许我们使用算子分裂方法,并用不同的数值方法单独求解这两个术语。用优化积分器精确地求解拉伸部分,这可以非常有效地完成,因为系统矩阵是随时间变化的常数,从而可以预先计算其Cholesky因子分解。通过使用柔顺约束方法和Gauss Seidel迭代近似求解体积项。进一步地, ...
