摘要
基于有限元理论,使用ANSYS有限元软件建立简单链形悬挂接触网的静态模型,分别采用分模法和负驰度法对模型进行计算对比,得到接触网的静态弹性,两种方法的仿真计算结果十分接近,均具有可行性。通过计算分析接触网张力和承力索张力对接触网静态弹性的影响结果表明,随着接触线和承力索张力的增大,接触网的弹性不均匀系数变小,更有利于高速列车的稳定受流。
Based on finite element theory, the static simulation model of stitched simple trolley- type catenary is established by using ANSYS finite element software, and the model is calculated and compared through using model partition method and negative relaxation method respectively, then the static elasticity of catenary is achieved. The simulation calculation results of the two methods are very close and feasible, Through calculating and analyzing the influence of catenanry tension and messenger wire tension on static elasticity of catenary, the result shows that following with increase of canternary tension and messenger wire tension, the asymmetry coefficient of catenary elasticity will diminish, which will be propitious to stable current collection of high-speed trains.
