Based on finite element software of ANSYS,a coupling heat structure model was put forward to analyze the frictional sliding of the shoe rail in Rocket Sled Track Test(RSTT).The temperature and stress field of the shoe in specific load and operating conditions was calculated.The results show that thermo physical parameters of the shoe materials and the friction coefficient have a great effect on the temperature of contract surface.With the friction coefficient increased,the temperature of contract surface is increased gradually.The result by the analysis of the thermal stress distribution in specific path shows that there are frictional heat affected zone and thermal stress concentrated zone in the contact surface upwards about 6 mm,in which the shoe is destructed during the operation.
