【 摘 要 】

An instrument that measures wheel-rail appearance is used to measure the size of the wheel and rail in the section of the Baishiqiao South Station of Beijing Metro Line 6 to develop a finite element entity. Different working conditions such as axle load and traction are considered. The results show that: Under axle load, the matching performance of wheel I/rail II is improved, its contact area is the largest, and its equivalent stress and contact force are minimal; Under traction force, the matching performance of wheel I/rail II is improved, and the shear stress and equivalent stress are minimal, and thus is ideal.
