摘　　要：为研究液力变矩器涡轮叶片结构强度是否满足要求,文中利用单向流固耦合分析技术对涡轮叶片结构强度进行了分析。首先,利用UG建立了液力变矩器3D模型;然后,利用CFX对液力变矩器进行了仿真计算;最后,将从CFX计算结果中提取出来的涡轮叶片上的压力施加到静力学结构强度分析的涡轮叶片上,利用ANSYS Static Structure对涡轮叶片静力学结构强度进行了静力学仿真计算。得到了涡轮叶片在不同工作状态下的等效应力分布和总变形情况。为涡轮叶片结构强度优化设计提供了准确、可靠的理论依据。In order to study whether the structure strength of torque converter turbine blade meet the requirement,this paper carries out structure strength analysis of turbine blade using the fluid-structure interaction analysis technique.Firstly,we establish the three-dimensional model of torque converter using 3D modeling software UG.Then,we perform simulation calculation of torque converter by using CFX software,apply the pressure load extracted from CFX results to the turbine blade on the static structure strength analysis,carry out statics simulation calculation of the structure strength of turbine blade using ANSYS Static Structure.The equivalent stress distribution and total deformation situation of turbine blade are obtained,which provide an accurate and reliable theoretical basis for the structure strength optimization design of turbine blade,under different working conditions.
