摘要
基于单向流固耦合(FSI)分析技术,对某型冲焊型液力变矩器的焊接强度进行数值计算。计算中依据冲焊型液力变矩器焊缝处的结构特点,采用接触算法,并通过CFD和FEA相结合的方法实现了对涡轮焊接强度较为精确的预测,同时得到了涡轮结构的变形和应力分布情况。结果表明在典型的制动工况下,冲焊型液力变矩器的焊接强度能够满足要求。本文工作可为冲焊型液力变矩器的结构设计及分析提供参考和指导。
The welding strength of a stamping welded hydrodynamic torque converter is calculated based on the Fluid-Solid Interaction （FSI） analysis technology. The calculation is based on the structural feature of a welding seam in stamping welded hydrodynamic torque converter. It applies contact algorithm, implements an accurate prediction of the welding strength of turbine by combining CDF and FEA. The distortion and stress distributions of the turbine structure are obtained. The results show that, under typical braking condition, the welding strength of stamping welded hydrodynamic torque converter can meet the requirements. This work provides an important reference to the structural design and strength analysis of stamping welded hydrodynamic torque converter.
