针对某型号瓦楞机的瓦楞成型系统，本文基于自主研发的多体动力学求解程序，建立了其刚柔耦合动力学模型。其中张力辊、瓦楞辊等主要支撑辊简化为刚体模型；传送带由36自由度绝对节点坐标四边形壳单元划分网格，并考虑其树脂材料的正交各向异性特征；此外，传送带与支撑辊之间的接触采用赫兹碰撞模型和点-面检测方法描述。利用该模型，计算了传送带的偏心位移，传送带表层应力场等动响应。仿真表明：本文基于绝对节点坐标法建立的瓦楞成型系统的多体动力学模型，可为瓦楞机传送带的动力学行为和控制研究提供一种新的分析方法。

Aiming at the adjusting mechanism of a certain type corrugating machine, the rigid-flexible coupled dynamic model was established base on an in-house developed solver for multibody dynamic system. Where the tension roll and the corrugating roll were considered as rigid body; The resin belt was modeled by 36-Dof Node 4 shell elements based on The Absolute Nodal Coordinates Formulation (ANCF), and the orthotropic characteristics of the resin belt was also considered; In addition, Hertz contact theory and the presented point-to-face measure method were adopted to describe the frictional impact between main rolls and the resin belt. By using this model, dynamic response such as the eccentric displacement and the surface stress distribution were calculated. The simulation result shows that the presented multibody dynamic model based on ANCF can provide a new analysis method for the research on the dynamic behavior and control of the resin belt in corrugating machine system.
