| 中文摘要: |
| 针对某矿用三轴重型自卸车因推杆失效而导致产品可靠性低的问题，建立了对橡胶采用C3D8H单元，对金属构件采用C3D8R单元和C3D4单元的平衡悬架用推力杆有限元分析模型。利用有限元分析软件ABAQUS对其进行了强度分析、模态分析和屈曲分析。有限元分析结果和推杆在实际使用中出现的异常断裂情况相吻合，找出了该车推杆裂纹过早出现的原因，并给出了推力杆改进设计的方法。实际改进结果表明:改进方法是有效的。 |

| Aimed at the problem of low reliability due to the failure of thrust bar of a heavy dump with three axis for mining, the finite element analysis model of thrust bar used in equalizing suspension was established, in which C3D8H units were adopted for the rubber components, and C3D8R units and C3D4 units were adopted for metal components. Using ABAQUS finite element analysis software, the analysis of its strength, modal and buckling were carried out. The results of finite element analysis match the case of crack of thrust bar in actual use. The reasons of premature cracks in the thrust bar were found out, and the improvement design of this thrust bar was given. Actual improved result has showed that the method is effective. |
