Abstract:

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.

Key words: fluid power transmission and control, stamping welded hydrodynamic torque converter, fluid-solid interaction, welding strength, contact algorithm
