【 摘 要 】

This study analyzed the thermal and stress field of a rocket sled slipper by establishing a thermal-mechanics coupling model. The temperature field and thermal stress field were obtained. The results are compared with real rocket sled run test. It shows that there is an agreement of wear distance between the test and simulation. However, the real test local temperature which is above 1470 °C, in evidence of detected Cristobalite-high SiO2, is much higher than simulation result which is 818 °C, due to high vibration impact load in real run test.
