▎ 摘　　要

NOVELTY - The method involves selecting the model parameters based on the actual graphene-copper based composite graphene content and mortar-brick masonry structure parameter. A pure copper model is established. The graphene is generated in the copper model. The fastest descent algorithm is used to minimize the energy of the model to optimize the model structure. The different working conditions, different graphene content and different surface temperature change rule of composite material are calculated. The temperature change rule is compared to graphene the best mass fraction and distribution mode of the heat-conducting performance. USE - Method of heat-conducting performance of copper-based composite material based on graphene doped used in electromagnetic ejection guide rail material design field. ADVANTAGE - The copper-based composite material heat-conducting modified design method is based on graphene, optimum graphene the material of the content and distribution mode, realizing the prediction and auxiliary manufacturing thermal conductivity the graphene-copper- based composite track material. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart illustrating the method of heat-conducting performance of copper-based composite material. (Drawing includes non-English language text)
