冲击载荷下开口式连接环动力学研究

Dynamics Study of Shackle Type Connector under Impact Load

为研究矿用开口式连接环在冲击载荷作用下的力学性能,采用Solidworks建立连接环实体模型,运用ANSYS/Ls-dyna对模型分别进行隐式-显式顺序求解和显式求解分析。通过分析模型运动和应力曲线,结果表明:链环间初始张力可以降低卡链产生的应力冲击。

In order to study the mechanical properties of the shackle type connector under impact load,Solidworks is used to establish the solid model of the connecting ring, and the ANSYS/Ls-dyna is used to analyze respectively the model by implicit-to-explicit sequential solution and explicit solution. The curves of motion and the equivalent stress show that the initial tension of the ring can reduce the impact stress.
