摘　　要：为了获得卷取机扇形板在卷取过程中所受的应力场分布情况,通过给出扇形板所受径向压力计算方法,建立卷取模型的物理方程,得出柱塞接触位置的正压力。对扇形板的接触情况进行讨论,给出相应的接触行为及其接触参数,运用Ansys有限元分析软件,得到扇形板与外部带钢接触时的等效应力分布图。将等效应力与同一时刻的温度应力相耦合,得到最终在实际工况下龟裂集中区的应力场,既弥补了生产过程当中无法直接测量扇形板应力大小的不足,又为进一步探究扇形板龟裂现象提供了有效的参考依据。In order to obtain the distribution of the stress field on the segment of the coiler during the coiling process,the calculation method of the radial pressure on the segment is given,the physical equation of the coiling model is established to obtain the positive pressure at the contact position of the plunger.The contact condition of segment is discussed to gain the corresponding contact behavior and contact parameters.Thus,the equivalent stress distribution diagram of segment contacting with external strip steel is obtained by applying Ansys finite element analysis software.The equivalent stress is coupled with the temperature stress simultaneously to gain the final stress field in the crack concentration area under the actual working condition,which not only makes up for the shortage that the stress of segment cannot be measured directly in the production oprocess,but also provides an effective reference for further exploring the cracking phenomenon of segment.
