To further study semi-trailer drive axle housing running and operating characteristics

taking semi-trailer axle for the study object

for the fracture and fatigue phenomena of driving axle trailer in motion process and the problem of the influence of actual bench test on enterprise research and development costs

by creating a virtual test bench

the test analysis and actual combine working condition characteristic analysis are carried out

the performance evaluation system of semitrailer axle is established.The law of drive axle housing stress

deformation and changes of life under the actual combine working condition and the standard bench condition is researched.The results show that

under the standard bench test conditions

the type of product performance meet the requirements of bench

under the actual conditions

this type of product stress

deformation parameters still satisfy the bench evaluation and use of materials properties.The fatigue life of the axle housing product obtained after analysis of the safety factor and fatigue life meet business requirements

through the comparative analysis of the result of the actual sample bench test with the results obtained by simulation bench test

it has guiding significance to the enterprise product development.
