Abstract
In this paper, through simulation and analysis technology, a rolling stock running in China's Ha Da line in low temperature -40 ℃ conditions, rubber parts, hydraulic damper stiffness and damping changes, as well as a system of spring and two system of spring freezing and freezing at the same time when the fault, the vehicle in different speeds, the old and new two tread state, the study of the vehicle system of snaking motion stability, operational safety and smooth operation, to obtain the vehicle dynamics of the low temperature state performance change law, the study shows that a system of spring and two system of spring freezing and freezing at the same time when the fault has a very serious impact on the vehicle dynamics performance.
