| Abstract: |
| Abstract：The mechanics calculation formula of tire mold slider was determined according to the actual
working condition. The fatigue life and safety factor of slider with different upper cantilever thickness and
material were simulated and analyzed by CAD/CAE and fatigue life analysis software. The results showed
that the fatigue life of the slider was significantly prolonged and the safety factor was significantly enlarged
as the thickness of the upper cantilever increased. The fatigue life of the slider made of 40Cr material was
longer than that of the slider using QT450-10 material，and the safety factor of the 40Cr steel slider was also
bigger. |
