A Simulate-Graphic System of Train Longitudinal Dynamics

The hardware and software of SGS (the Simulate-Graphic System of train longitudinal dynamics) is discussed in this paper To increase railroad trafflc volume, we have studied train dynamics and programmed SGS, combining numerical simulation methods with computer graphic techniqne SGS can well simulate train ope rations, and analyze train performances. The results of SGS are good in reliability, and it has been applied in the oew Da-Oin heavy haui line.
