Abstract Automobile mesh is a typical large plastic part prone to warping deformation in the manufacturing process, which seriously affects quality of products. The traditional method find optimal combination parameters reduce forming process through repeated trial or mold flow analysis with high cost. In this study, An optimization based on an artificial intelligence algorithm proposed optimiz...

The warpage prediction accuracy of the simulation software depends on part geometry, material model and methodology. However, in existing software’s does not consider factors such as nonlinear mechanical properties, temperature dependent behaviour, viscoelastic behaviour transient description leading to less accuracy. Using an integrative approach, BASF has developed Ultrasim® tool overcome lim...

The vibration attenuation mechanism of shear thickening fluid- (STF-) filled sandwich structures was investigated in this study. Structural equivalent damping, stiffness, and mass increased simultaneously with the increase volume fraction fluid. However, damping ratio decreased natural frequency structural mass. Thus, not a monotonically increasing function STF. A modified strain model layer de...
