Aiming at the problem of the fatigue failure of the wheel loader drive axle housing

by using fatigue failure theory

the theoretical and finite element modeling of wheel loader drive axle housing work characteristic is carried out.The law of fatigue failure of wheel loader is studied

a calculation model to predict drive axle housing fatigue failure is proposed.The results show that as computing model considers the random load spectrum and the corrected stress fatigue curves

the wheel loader drive axle failure model fit the actual

the wheel loader drive axle wheel rim section dramatic change location exists stress concentration regularity

the first six orders natural frequency values are far from the actual condition of the road surface excitation frequency

the wheel loader drive axle housing damage occurred mostly in the low stress amplitude under.
