Taking into consideration the influence of contact angle during the process of pantograph/catenary sliding contact,the Lankarani Hertz contact model was modified and a new pantograph/catenary contact model was proposed.The effects of using the traditional contact model,the Lankarani Hertz contact model and the proposed model,on the dynamic performances of a pantograph/catenary system were investigated.The results show that compared with the traditional contact model,the Hertz contact model considers the effect of damping between pantograph and catenary,and makes the contact force variation much gentler.For the new contact model,the contact force variation becomes more severe than that of the Lankarani model at high speed,especially in the vicinity of the registration; At high speed,the influences of the damping between pantograph and catenary and the contact angle can not be neglected,and it is more reasonable to adopt the new contact model to perform pantograph/catenary dynamic simulations.
