摘要

本文采用有限元法建立了轧辊张紧过程的二维简洁快速模型。采用弹性热膨胀法模拟轧制塑性变形。建立了考虑滚轮与圆锯片接触的三维模型。通过对比二维模型、三维模型和x射线应力测试方法得到的残余应力结果，验证了二维模型的正确性和可行性。考虑到圆锯片结构的多样性，为快速预测滚张圆锯片的残余应力场提供了思路。

An Idea for Predicting Residual Stress Field of Roll Tensioned Circular Saw Blade

In this paper, a concise and fast 2D model of the roll tensioning process was built using the finite element method. Elastic thermal expansion is used to simulate rolling plastic deformation. A 3D model considering contact between roller and circular saw blade was also built. Through comparison of residual stress results obtained by the 2D model, 3D model, and X-ray stress test method, the correctness and feasibility of the 2D model were proven. While accounting for the diversity of circular saw blade structure, this paper provided an idea for rapidly predicting the residual stress field of a roll-tensioned circular saw blade.

期刊介绍： Forest Products Journal (FPJ) is the source of information for industry leaders, researchers, teachers, students, and everyone interested in today''s forest products industry. The Forest Products Journal is well respected for publishing high-quality peer-reviewed technical research findings at the applied or practical level that reflect the current state of wood science and technology. Articles suitable as Technical Notes are brief notes (generally 1,200 words or less) that describe new or improved equipment or techniques; report on findings produced as by-products of major studies; or outline progress to date on long-term projects.
