随着熔丝制造技术的日益广泛应用，其制品不可避免地会受到动态机械载荷和振动的影响。然而，关于FFF产品的动态力学性能的理解和表征的文献中还没有系统的研究。本文在考虑不同挤压宽度影响的情况下，对FFF板的动态特性进行了量化。建立了具有悬臂边界条件的组合板的动力学模型，并对其固有特性进行了预测。然后对这些样本进行模态试验，以获得测量数据。通过预测值与实测值的比较，验证了理论模型的正确性。不同的挤压宽度会使板材的材料性能不同，从而产生不同的动态特性。样品的扫描电子显微镜(SEM)分析证实，随着挤压宽度的减小，动态特性变差。本文的工作为进一步研究提高FFF产品的动态性能提供了理论依据和技术支持，有助于推广该技术的应用。
With the increasingly wide application of fused filament fabrication (FFF) technique, the built products are inevitably exposed to dynamic mechanical loading and vibration. However, there has been no systematic study in the literature on understanding and characterization of dynamic mechanical performance for FFF products. In this paper, the dynamic characteristics of FFF plates are quantified, with the effect of different extrusion width taken into account. A dynamic model of the built plate with cantilever boundary conditions is established, and the inherent characteristics are predicted. Modal tests are then performed on these samples to obtain the measured data. Through the comparison between predictions and measurements, the theoretical model is validated. Different extrusion width makes the material properties of the plates different, resulting in different dynamic characteristics. The scanning electron microscopy (SEM) analysis on the samples confirms that the dynamic characteristic is deteriorated as the extrusion width decreases. This present work provides theoretical basis and technical support for further research in improving the dynamic performance of FFF products and helps extend the applications of this technique.
