| 摘 要： | 基于非线性接触动力学,建立了圆环链模型,运用有限元动力学分析软件ANSYS/LSDYNA对圆环链间的接触碰撞过程进行了仿真分析。分析结果表明,冲击导致的磨损是造成链环断裂的主要原因。给出了圆环链断裂的主要位置,从而为研究矿用圆环链装置的损伤和寿命估算提供了理论依据。

| Abstract: | Based on nonlinear dynamics, a round-link chain model is established,the contact between the round-link chains is simulated with the finite element dynamic analysis software ANSYS / LS-DYNA. The results show that wear is the main cause leading to the fracture of round-link chain. The study shows the main fracture location to provide a theoretical basis for the research of damage and life estimation about round-link chain. |
