摘要

单面瓦楞机在成型的过程中存在较大的振动,为了分析振动的原因及减振,本文对单面瓦楞机的关键机构——光辊机构进行动力学建模,发现推杆刚度不足,造成光辊机构的非线性。进行振动测试,验证了动力学模型的正确性,得到单面瓦楞机振动的主要原因:单面瓦楞机在正常工作转速范围内,存在两个共振频率。最后对光辊机构提出改进方案,并仿真对比改进前后光辊机构在受迫振动下的振动位移,改进后的位移幅值降低了35.2%。研究结果为降低瓦楞机的振动提供了理论依据。

Abstract

In the process of paper forming,serious vibration is usually existing in a single-sided corrugating machine. In order to analyze the causes of vibration and thus reduce it,a dynamic model was set up to study the key mechanism of the single-sided corrugating machine—the pressure roller mechanism. The simulation results show that it is the insufficient stiffness of the push bar which causes the nonlinearity of the pressure roller mechanism. An additional experiment was carried out to verify the validity of the dynamic model,from which the main reason resulting in the vibration of the machine was revealed. It turns out that the single-sided corrugating machine has two resonance frequencies when it works within the normal rotating speed range. Finally,an improvement solution was proposed to control and reduce the vibration by increasing the stiffness of the push bar. Simulation comparisons show that the forced displacement of the mechanism is reduced by 35.2 percent using the improvement solution,which provides a theoretical reference for reducing the vibrations of corrugating machines.
