Study On Rigid Suspension Catenary System And Application

Rigid Catenary System characteristics are important factors of related to bows follow Contact and train locomotive flow stability and reliability, the finite element method is the analysis of such problems in an effective manner. In this paper, use the finite element method for dynamic analysising the overhead rigid catenary system, While comparing or analysising the study results and practical application .First introduced the basic of profiles overhead rigid catenary and overseas/ domestic applications and the present situation, according to domestic and foreign fixed rigid catenary layout requirements, in not considering the pantograph dynamic effects of the circumstances, to overhead rigid catenary for static calculations, and the elevation of force and the results of the field tests deviation analysis.Consider rigid catenary and the pantograph are the dynamic factor of influence on each other. Under the current Rail Transit Project's the locomotive formation and the pantograph type, quantity, consider the future of passenger traffic, focus on 3 pantograph dynamic analysis. In this paper, using Lagrange equation derived by the pantograph of nonlinear equations of motion, adopting nonlinear model in a certain altitude done linear processing, to be lumped quality of the pantograph vertical linear model;By establishing rigid catenary,the pantograph, the strap parameters and dynamic model, using Fortran programming with determinant search method to work out their natural frequencies and mode pantograph by a linear model and the catenary finite element model. Through coupling of pantograph / rigid- catenary, use Fortran language and their programming doing dynamic simulation. To speed, span and the stiffness of flag point by the effect of flow simulation, raised layout of the special guidance. Under domestic and external situation to arrive at the actual flow indicators and standards.Dynamic simulation of rigid catenary design optimize some important issues to the span and the anchor of the joints, provide theoretical basis, while Dynamic simulation raised requirements to relevant professional tunnel structure, orbit design.Stiffness of Rigid catenary flag points, swelling of the components used, to simplify the calculation of strap such difficult issues be raised closer to expectation.
