摘要

基于单向流固耦合理论建立了某型液力变矩减速装置叶轮有限元强度分析模型，分析了模型的载荷及边界条件，进行了求解计算与结果后处理。通过实例分析，研究了液力变矩减速装置叶轮在变矩工况下结构强度问题，得到了各工作轮极限工况的等效应力分布和总体变形量，为液力变矩减速装置叶轮强度分析提供了一种有效的方法。%A finite element hydrodynamic tractor-retar boundary conditions and t reprocessing were conducte of the hydrodynamic tractor-retarder was studied under the traction distribution and the overall deformation state of the blade wheel obtained.
