rubber tie-plate

The finite element model, which is composed of JM_2 worn type of locomotive wheel, standard 60 kg/m rail, rail fastening, rubber tie plate and ballast bed, can simulates actual wheel/rail contact state well.
本文的有限元模型包括機(jī)車JM_2型磨耗型踏面、60kg／m鋼軌、扣件、橡膠墊板和道床等，這樣能更加真實(shí)地模擬了輪軌接觸狀態(tài)。
