Study on the Snake-Like Movement of High-Speed Railway Vehicles Based on Steady-State Vibration Theory of the Center of Mass
Abstract: By analyzing the relationship between the various degrees of freedom of the body and the car body mass center transverse vibration, the establishment of a simplified model of the vehicle center of mass lateral vibration analysis, and on this basis, the use of the vibration condition of stable equilibrium system to prove that the support of gravity and track surface power is the root cause of the car center of mass in the lateral vibration of rail surface, and thus derive the relationship between the turnout center of mass transverse vibration frequency of the wheel tread taper, found that when the wheel tread taper ≥ 1/40, vehicle physical the lateral vibration of the heart is stable. Based above and combined with different speed and different lateral vibration frequency, the snake-like movement wavelength of the train vehicle was discussed, as the further step, the lateral force induced by snake-like movement and effected on the orbit was discussed deeply, it is found that the value of the force is in the range of 5% to 20% of the vehicle weight, the given specification (10% of the vehicle weight) is just located in this range.
