| Abstract: |
| The displacement data of screw surface,the regular patterns of stress distribution and the vulnerable damaging places of auger have been obtained through the finite element calculation and analysis of screw auger of hole digger. Also, the factors affecting the strength and the rational scope of value counts of parameters for auger structure are found out through the changes in structural parameters of auger and the simulation contrast tests. The calculated values are in coincidence with the practical ones.As a result,the calculation model and the method are feasible,thus, laying a solid foundation for the optimal design of auger of hole digger. |
