圆锯片在木材加工中应用非常广泛。它们以不同的批次和尺寸使用，从手工工具到大型加工中心都有大量使用。由于这种巨大的应用范围，圆锯在工业中获得了很大的重要性。提高锯切质量、降低噪声、提高使用寿命的要求越来越高，这就要求对圆锯片的动态特性采取改进措施。圆锯片的辊张紧已被经验地确立为改善圆锯片的静态和动态特性的优雅解决方案。然而，这个过程中有几个影响参数尚未得到科学准确的研究。建立基于有限元法的仿真模型，分析不同辊系张紧参数对圆锯片动态性能的影响，是研究辊系张紧参数变化规律的一种科学、经济的解决方案。在这项工作中，圆锯片辊张紧的仿真模型。利用该模拟模型，可以计算出轧辊张紧引起的残余应力。这对于改变圆锯片的动态特性，如特征值的移动和减少侧跳动是非常相关的。此外，该模拟模型允许研究各种辊张紧参数。本文的研究有助于更好地理解辊张紧与圆锯片动态性能改善之间的关系。此外，它有助于找到辊张紧过程的优化潜力，这是圆锯片生产线的最重要的部分之一。
Circular saw blades are very widespread in wood machining. They are used in different batches and sizes and in large quantities from hand tools to large machining centers. Because of this huge range of applications the circular saws have gained great importance in the industry. The rising request to improve the cutting quality, reduce the noise emission and increase the life time requires improvement measures for the dynamic behavior of the circular saw blade. The roll tensioning of the circular saw blade has been empirically established as an elegant solution to improve the static and dynamic properties of the circular saw blade. However, there are several influencing parameters for this process that have not yet been studied scientifically accurate. A scientific and economical solution for the study of various roll tensioning parameters is a simulation model based on finite elements method (FEM) that analyzes the effects on the dynamic behavior of circular saw blade. In this work, a simulation model for roll tensioning of circular saw blades is presented. With this simulation model, the residual stresses induced by the roll tensioning can be calculated. This is very relevant for the changing of dynamic properties of the circular saw blade, such as the shifting of eigenvalues and reduction of side run out. Furthermore, this simulation model allows the investigation of various roll tensioning parameters. This investigation helps to gain a better understanding of the relationship between roll tensioning and improvement of dynamic behavior of circular saw blades. Furthermore, it helps to find the optimization potential of the roll tensioning process which is one of the most important parts of the production line of circular saw blades.
