ANSYS Workbench software was used to evaluate the fatigue life of the weld of the aluminum alloy intermediate frame of a certain type of subway windshield,and the fatigue load condition was applied to the intermediate frame according to the EN 12663 standard,and the utilization rate was calculated by using the DVS1608 multiaxial stress evaluation method based on the stress simulation result.The evaluation result shows that the utilization rate under all working conditions is less than 1,indicating that the weld of the aluminum alloy intermediate frame of the subway windshield meets the use requirement.
