摘　　要：本文利用ANSYS软件,针对制动轨与轨道轨面不同高度、列车直线行驶和弯道行驶两种情况下的变形和受力进行了仿真计算,结果表明,轮轨应变量会随制动轨与轨道轨面高度变化而变化,两种行驶线路下轮轨应力分布受制动轨与轨面高度变化的影响不大,此结果为防溜器的设计和在大坡度铁路到发线的推广应用提供了理论依据。According to the different situation of force and deformation such as the braking rail to rail surface with ditterent tleight, the train is moving in a straight line and curve running was calculated by simulation. The results show that the deformation varies will change with the change of the height between brake rail and rail surface, but wheel and rail stress distri- bution under two kinds of driving circuit changes little. The results provides anti slip device in steep slope railway line＇s theorctical basis for its design and widely application.
