接触性特征有限条在冷弯成形过程中的应用研究

冷弯型钢是广泛应用的型材,其轧制质量由孔型决定。现有的孔型设计主要依靠经验公式和经验参数,所以设计的孔型往往需要实际修正。笔者提出的方法可以为设计孔型提供理论依据,可以减少大量的数据冗余。特征有限条中的接触性特征有限条能够较好地解析钢带的变形过程,对孔型设计的智能化起着指导性的作用。

Application research of contact characteristic finite strip in the process of cold roll form

Cold-formed steel is a widely applied material,and its rolling quality is decided by pass.Available pass design mainly depends on empirical formula and empirical parameter,so the designed pass often needs actual correction.The method proposed in this paper can provide theoretical basis for design pass and decrease abundant redundancy data.The contact characteristic finite strip of characteristic finite strip can better ananlyze the deformation process of steel strip,which provides instructive effect to the intelligence of pass design.
