| Abstract: | High-speed railway
belongs to complex system engineering, in which a series of key
mechanics problems are involved. The present paper discusses three
key problems of solid mechanics existing in high-speed railway
engineering, i.e. wheel-rail rolling contact mechanics, fatigue of
high-speed train components and dynamic interactions between
high-speed trains and infrastructures. The latest advances in
these research areas are reviewed as well as their applications to
high-speed railway engineering. Some suggestions for future
studies are offered based on the demand from high-speed railway
engineering practice. |
