Abstract:A finite element analysis method was used to simulate the stamping process of the blade of a large concrete-mixer truck. The updated Lagrange method and the elasto-plastic constitutive equation were adopted to solve the large strain and displacement deformation of the blade. A modified Coulomb friction model was used to solve the sliding contact between the blade and the dies. The von Mises stress distribution in the blade, the spatial displacement variation and the spring-back of the typical node were investigated in the simulation. The von Mises stress in the blade where the spring-back occurs is lowered from 463.0 MPa to 150.0 MPa before and after the spring-back.A typical node in the blade has a 3.33 mm spring-back inZdirection. The results of the experiments agree well with the simulation. The analysis results are valuable for designing optimal tool dies.
