摘　　要：将轧后板带离散为若干纵向条元,用三次样条插值函数和正弦函数构造振型函数,根据动力学准则,将板形失稳判别归结为板形判别因子的求解。计算实例表明,本方法可靠、实用。The rolled strip is divided into a number of strip elements on the vertical, the deflection function model is constructed with the third - power spline function and the sine function. From the dynamics, the shape discrimination is transformed into the solution of shape discrimination factor. The computed examples prove the reliability and the practicality of this method.
