摘　　要：固相缩聚反应器在分析设计过程中,由于需要考虑反应器和物料自身的重力、反应器的旋转条件等复杂边界条件,又由于对固相缩聚反应器的一次应力、二次应力和峰值应力没有具体的评定准则,在对其进行应力强度的评定中没有统一的评定方法,这就给实际的工程设计带来了很大的困扰。因此,以实际工程设计要求为基础,采用有限单元法对反应器模型进行数值模拟,增加反应容器、喷嘴、螺栓等部件的边界条件,再通过应力线性化对有限元分析结果进行一次应力和二次应力的判定,最终对整个固相缩聚反应器进行强度评定。该方法为固相缩聚反应器的设计提供了一定的理论基础,并给实际工程应用提供了一定的参考。In the process of analyzing the design of solid-phase polycondensation reactors,complex boundary conditions such as the gravity of the reactor and the material itself,and the rotation conditions of the reactor need to be considered.At the same time,because there is no specific evaluation criterion for the primary stress,secondary stress and peak stress of the solid-phase polycondensation reactor,there is no unified evaluation method in the evaluation of its stress strength,which brings great trouble to the actual engineering design.Based on the actual engineering design requirements,the finite element method is used to numerically simulate the reactor model,the boundary conditions of the reaction vessel,nozzle,bolt and other components are applied,and then the primary stress and secondary stress are determined by the finite element analysis results through stress linearization,and finally the strength of the entire solid-phase polycondensation reactor is evaluated.This method provides a certain theoretical basis for the design of solid-phase polycondensation reactor and provides a certain reference for practical engineering applications.
