Analysis on Static Strength of Bogie Frame based on Finite Element
The static strength finite element simulation analysis was carried out for the bogie frame of a 110 t special molten iron transport vehicle,and the stress concentration point of the frame was determined.The static strength test bench of the whole bogie is designed and manufactured,and the standard TB/T3549.1-2019 stipulates the load loading requirements.Based on the test bench,the static strength test was carried out to evaluate its static strength and fatigue strength.The results show that the weak position of the bogie frame is located at the welding position of the cross beam and the bending position of the cross beam.Under the condition of abnormal load,the test stress of the frame is 144.69MPa.Under the simulated operating conditions,the maximum stress of the frame is 132.81MPa,which meets the static strength requirements.The fatigue strength is evaluated by Goodman diagram.The results show that the test results of each measuring point are within the envelope of Goodman diagram,which meets the requirements of fatigue strength.
