| Abstract: | The frame is the load-bearing foundation of straddle-type monorail vehicles,and the strength and reliability of its welded structure are related to the safety of vehicle operation.During the operation of the straddle-type monorail vehicle,the frame is excited by the road surface of the track beam and the impact of the finger plate.In order to improve the fatigue calculation accuracy of the frame weld structure,this paper considers the influence of the inherent dynamic characteristics of the frame structure on the fatigue performance,and establishes a set of fatigue calculation and analysis methods. |
