【Abstract】 With the increasing in locomotive speed, the demand for dynamic performance of locomotive transmission system is higher. This paper analyzes the forced vibration response of transmission system in 200km/h AC electric locomotive during its starting period, establishes the calculating model of the driving system by using mode superposition method, calculates the forced torsional vibration response of transmission system and the dynamic load magnification factor; and analyzes the influence of excitation function and damping on response results.更多还原
