Article Preview

Based on the performance of new Cu-Cr alloy strip, triplet self-elastic contact fingers by traditional copper material were analyzed. Through the finite element numerical simulation and DOE sensitivity analysis, it is determined that thickness was the key parameter which impacts the contact fingers structure. Then the structure parameters were optimized. The results show that after optimization, thickness of contact fingers by traditional copper material decrease to 3.43 mm from 5 mm, the maximum equivalent stress is 315.37 MPa, the maximum shear stress is 181.24 MPa, the maximum deformation is 2.55mm, and the mass is reduced about 30%.
