Abstract
Numerical simulation program based on the finite difference method (FDM) to analyze two-dimensional dynamic behavior of pantograph/catenary system has been being used for researches, developments, and operations of electric railways for a long time. However, the finite element method (FEM) is more suitable to care its three-dimensional dynamic behavior with large displacement. Therefore, the author newly developed a new simulation program based on FEM, which can analyze dynamic behavior of catenary with three-dimensional configuration, such as inclined catenary system.
