| Abstract: | Special vehicle used in the bad road conditions for long-distance transportation,the strength and vibration characteristics of bearing components have higher requirements.In view of the welding seam cracking of a cargo hold support beam in use,the simulation model of the beam was established,the vibration characteristics and structural strength were simulated and analyzed,and the results were compared with the experimental results.The results show that the simulation results are basically consistent with the experimental results,and the optimization of component structure and the improvement of reliability are realized. |
