In order to study the stable dynamic performance of type HXD1 heavy haul locomotive coupler/draft gear system in line experiment,resilient rubber draft gear with nonlinear hysteretic characteristic and coupler simulation model with frictional globoid on coupler tail are developed,based on the analysis of 13A/QKX100 coupler/draft gear system's unique working mechanism.Dynamic characteristic of 13A/QKX100 coupler/draft gear system bearing longitudinal pressure is studied.Effect of frictional globoid on coupler tail to dynamic behavior of coupler is analyzed in comparison.Study results show that,the models that developed in this paper could simulate the dynamic performance of coupler/draft gear system which used on type HXD1 heavy haul locomotive with considerable precision.The frictional globoid is shown to be significant factor in control of coupler's dynamic behavior.
