基于ADAMS的瓦楞辊动力学仿真分析

Dynamic Simulation Analysis of Corrugated Roller Based on ADAMS

目的根据瓦楞辊的啮合特性和工作环境,分析有无瓦楞纸及不同转速对瓦楞辊工作时中心距变化的影响,为提高瓦楞辊机构转动的平稳性提供理论依据。方法首先运用三维建模软件CREO建立上、下瓦楞辊和瓦楞纸的三维模型,然后运用动力学分析软件ADAMS对瓦楞辊的运动过程进行仿真分析。结果从仿真结果中得出了无瓦楞纸、有瓦楞纸和转速不同的情况下瓦楞辊中心距变化曲线,并将得出的曲线进行了对比和分析。无瓦楞纸时上、下瓦楞辊的中心距变化量在0.45 mm之内,有瓦楞纸时上下瓦楞辊的中心距变化量在0.045 mm之内。结论瓦楞纸的存在能够减小瓦楞辊中心距的变化量,使瓦楞辊机构的转动相对于空转时的转动更平稳,瓦楞纸的存在有利于减小瓦楞辊的振动及磨损;转速对瓦楞辊中心距的变化影响较小,可以通过适当提高转速来提高瓦楞纸的生产效率。

According to the meshing characteristics and working environment of corrugated roller,the influence of corrugated paper and different rotation speeds on the change of center distance of corrugated roller are analyzed to pro-vide a theoretical basis for improving the rotation stability of corrugated roller mechanism.Firstly,the 3D modeling software CREO is used to establish the 3D model of the upper and lower corrugated rollers and corrugated paper,and then the dynamic analysis software ADAMS is used to simulate the motion process of the corrugated roller.From the simula-tion results,the curves of the center distance of the corrugated roller under the conditions of no corrugated paper,with corrugated paper and different rotation speeds are obtained,and the curves are compared and analyzed.When there is no corrugated paper,the change of the center distance between the upper and lower corrugated rollers is within 0.45 mm.When there is corrugated paper,the change of the center distance between the upper and lower corrugated rollers is within 0.045 mm.The existence of corrugated paper can reduce the variation of the center distance of the corrugated roller and make the rotation of the corrugated roller mechanism more stable than that at idle.The existence of corrugated paper is conducive to reducing the vibration and wear of the corrugated roller;The rotation speed has little effect on the change of the center distance of the corrugated roller.The production efficiency of corrugated paper can be improved by appro-priately increasing the rotation speed.
