摘要

针对刮板输送机链传动系统负荷启动动力学行为与接触响应，以某型号重型刮板输送机机尾部链传动系统为例，建立了其刚柔耦合动力学分析模型与接触计算模型，详述了建模过程与方法，进行了链传动系统刚柔耦合动力学仿真与接触计算，并对计算结果进行了讨论和分析。根据计算结果，某型号重型刮板输送机链传动系统负荷启动对圆环链与链轮产生较大冲击应力与荷载变形，链环间接触处、链环直臂到弯臂过渡部分以及链轮齿根与链窝处变形较大，且有应力集中现象，需对链环节距、啮合间隙与链窝结构进行优化设计。

Abstract

Aiming at the dynamics behavior and contact response of the chains drive system of scraper conveyer under the state of loading start-up, the rigid-flexible coupling dynamics simulation model and contact analysis model are built, taking the chains drive system in drive end unit of a certain type heavy scraper conveyer for example. The modeling process and method are introduced in detail, and the rigid-flexible coupling dynamics simulation and the contact analysis are carried out. The results show that the significant shock stress and load deformation are appeared on the round-link chains and chain wheel. The obvious stress and deformation variation occur mainly in the contact point and the curve of the round-link chains and in the tooth root and the socket of the chain wheel. In consequence, the optimization design should be carried through on the round-link pitch, the gearing backlash and the chain wheel socket shape of the chains drive system.
