H型钢辊式矫直压弯挠度的计算一直难于得出适用工程的解。通过有限差分法的合理运用,结合符合实际的力学模型,给出了一种求解压弯挠度的实用方法,经过与目前工程上采用的确定挠度的方法比较,该方法更严谨、合理,有一定实用价值。

It is difficult to get a proper practical answer of bending deflection for H-Beam roller straightening.In this paper,based on adequate mechanics model and finite difference calculus,a practical method to solve bending deflection is put forward.Compared with the engineering method,it is shown that this kind of method is more reasonable,precise and useful.
