According to the characteristic and the precision demand, it improved the electric calculation method of surface charge. Mechanical Performance Analysis of Open Spandrel Rigid-Framed Arch Bridge 根据电场计算方法和物理模型建立了空腹式接地装置的计算等效模型。空腹式刚架拱桥受力特性分析
Comparing with previous methods, when the microstructures undergo small deformations, the surface charge densities on the deformed geometry can be computed without updating the geometry of the microstructures using the new approach, so the computational efficiency for coupled electromechanical analysis is improved effectively. 同以往的常规算法相比,当微结构变形微小时,使用该方法,微结构变形后的面电荷密度可以在微结构未变形中计算,从而大大提高了静电-结构耦合数值计算效率。
