【 摘 要 】

According to the fourth strength theory, this paper adopted equivalent stress to simulate fatigue life. Firstly, ANSYS was used to simulate equivalent stress in single-row welding, and variance analysis was used to analyze and process the simulation results to obtain the effect law of horizontal spacing and diameter of welding spot on the stress. Then, the equivalent stress of corrugated plate component, which was welded in triangular solder joint arrangement, was analyzed and treated with the method of variance analysis, and the effect law was obtained. In terms of the structure parameters of welding spot, the left and right margin of welding spot in the first row is 10 mm, 7 in number, and the center of the welding spot is 3.5 mm away from the upper boundary; the left and right margin of welding spot in the second row is 91.7 mm, 6 in number, and the center of the welding spot is 4.5 mm away from the upper boundary; both rows have a diameter of 5 mm and a horizontal spacing of 163.3 mm. Moreover, the actual fatigue life of physical test is more than 2.0E7 times, meeting the requirements of the working condition.
