摘　　要：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.
