As an important part of the contact suspension of OCS of high-speed railway,the fatigue characteristics of the electrical connection influence the performance of pantograph-catenary system.The dynamic parameters are obtained through study on fatigue characteristics of electrical connection,however,the dynamic parameters of electrical connection measured at site are prone to be influenced by the environment,so it is necessary to obtain its dynamic parameters with the help of simulation tools.Based on Hooke's law,an experimental platform is designed and established to measure the stiffness of the electrical connection,a finite element model of the electrical connection is established by means of the finite element method for comparison of test data after identical excitation simulation and calculation of electrical connection and verification of the effectiveness of the finite element of electrical connection.And the vibration load spectrum is obtained with taking of Wuhan-Guangzhou high-speed railway as an example.
