Study on comparison analysis of planar and 3D numerical methods during wedge-caulking process of one-way clutch

For one-way clutch of integrated hydrodynamic torque converter with logarithmic spiral mold surface, the stress distribution of roller, internal and external ring in the transient wedge-caulking process was investigated. Based on explicit dynamics, two-dimension planar strain and three-dimension finite element analyses were carried out, and this transient process was investigated numerically from the viewpoint of two-dimension and three-dimension respectively. Simulation results show that, compared with the planar strain analysis, the three-dimension analysis can provide axial stress distribution of each part, and the simplification from three-dimension to two-dimension analysis is feasible, and the consistency of calculation results derived from two analysis methods provides more reliable theoretical foundation for the design and calculation of one-way clutch.
