摘要：横向刚度是影响圆锯片锯切过程稳定性的重要因素。以四种具有代表性的圆锯片基体结构为研究对象,利用非线性有限元法建立其力学模型,研究在温度、离心力载荷单独作用以及两者共同作用下,圆锯片横向刚度的变化规律。结果表明:随着圆锯片外缘温度的升高,其横向刚度呈下降趋势;离心力载荷可提升圆锯片的横向刚度;圆锯片基体结构对于其横向刚度随圆锯片外缘温度的变化规律具有影响。
The transverse stiffness was an important factor affecting the stability of circular saw blade during cutting process.In this paper,four typical structures of circular saw blades were taken as the research objects,and their mechanical models were established by nonlinear finite element method.The variation of transverse stiffness of circular saw blades were studied under the centrifugal force alone,temperature field alone,and under both conditions respectively.The results showed that transverse stiffness of circular saw blade decreased with increasing sawing temperature while the centrifugal force strengthened the transverse stiffness of circular saw blade.The structure of circular saw blade has an influence on the change of its transverse stiffness with the temperature load.
