钢轨接头应力的有限元分析

Finite Element Analysis of Stress in Rail Joint

摘要: 利用有限元软件ANSYS建立了钢轨接头的三维计算模型,分析了螺栓转矩变化对接头区钢轨应力、接头夹板应力和螺栓应力的影响.结果表明,对于一般接头,螺栓转矩不应超过600~700 N·m;对于“冻结”接头,螺栓转矩的合理范围为900~1 000 N·m.

Abstract: A three dimensional calculation model of rail joint is proposed using finite element software ANSYS. The effect of bolt torque on stresses in rail, joint bars and track bolts in a rail joint is analyzed. The calculation results showthat reasonal bolt torque ranges from 600 to 700 N·m for a common joint and 900 to 1 000 N·m for a“frozen”joint.
