摘　　要：机架是整个轧机的重要组成部分,分析了整体式机架和组合式机架的特点。利用有限元软件ANSYS对组合式机架进行了有限元仿真计算,并进行了不同预紧力的影响和机架承载的应力应变分析;根据有限元仿真分析结果得出了组合机架的最佳预紧力范围和组合机架的薄弱环节,并对整体式机架和组合式机架在同等载荷下的应力应变进行了对比分析,证明了在工作中两者可以相互替代。The rolling-mill housing is an important part of the whole rolling mill.The characteristics of integral rolling-mill housing and sectional rolling-mill housing are analyzed.The finite element simulation of the sectional rolling-mill housing is carried out by using the finite element software ANSYS,and the influence of different preloads and the stress-strain analysis of the rolling-mill housing are carried out.The results of the finite element simulation analysis shows the best preload range and the weak link of the sectional rolling-mill housing.The stress and strain of the integral rolling-mill housing and sectional rolling-mill housing under the same load are compared and analyzed,which can be replaced each other in the work.
