PURPOSE: A driving stability analysis system of a railway vehicle is provided to calculate the total amplitude value of acceleration data through a driving stability analysis unit. CONSTITUTION: A vehicle acceleration measuring unit(100) measures vibration acceleration through an acceleration sensor. A tachosensor(200) measures the rotation of a wheel. The tachosensor is installed to measure speed and distance of a vehicle. An acceleration and tacho wireless data logger(210) amplifies data which the vehicle acceleration measuring unit measures. A vehicle stability analyzing unit(300) analyzes driving stability of a railway vehicle.
