Mechanical Property Analysis of Off-The-Road Tire for All-terrain Crane on Different Characteristics Pavement
The finite element model of 385/95R25 off-the-road tire for all-terrain crane with tread pattern was established.On the basis of verifying the accuracy of the model,the mechanical property of the tire on different characteristic roads(plane road,transverse boss and longitudinal boss)was analyzed.The finite element simulation results of tire inflation peripheral dimension and grounding data were consistent with the testing results,which proved the finite element model was accurate and reliable.The finite element simulation results showed that,the stress at the shoulder of the tire was concentrated at the end of the 2#belt,and the extreme value of strain was also here,the stress and strain of shoulder were relatively large under the condition of transverse boss.Under the condition of transverse boss,the cord tension of 1# belt increased obviously,and the carcass cord tension decreased in the contact area of boss.Under the condition of longitudinal boss,the cord tension in the contact area near the longitudinal boss at the end of the 1# belt increased,and the cord tension of the carcass changed little.The envelope stiffness of the tire was about 3 000 N·mm-1.The ultimate tear energy of the tire in the damage case was 672 J,and the tear energy index had important reference significance for formula designs.
