| Abstract: | Aimed at deviation between theoretical fatigue strength analysis results of hub bearing unit and actual vehicle fatigue strength test results,the strain test system is introduced to calibrate the load,and the real-time strain of hub bearing unit in bench test and vehicle fatigue strength test is obtained by actual vehicle fatigue test.The real-time loading condition of hub bearing unit is that the strain amplitude of right hub bearing is higher than that of left hub bearing,and the peak and valley of strain are asymmetrical.By modifying corresponding theoretical analysis conditions,the deviation between theoretical fatigue strength analysis results of third-generation hub bearing unit and vehicle fatigue strength test results is reduced from 54.9%to-4.78%. |
