A Force Model for UHSS Hot-formed Automobile Parts

摘要：

　　Combined numerical simulations and experimentally measured data, the relationship between the initial temperature of the workpiece was described, the stamping speed, and the required forming force.Air cooling was included to determine the temperature of the part within the mold, and the required stamping force was optimized by studying the impact of the cooling time on the temperature of the part.The optimized model was verified and validated by comparing simulated data for an anti-collision beam with the experimental results of the hot-forming process.The results showed that the model provides a useful description of the hot-forming process; however, an empirical factor of 0.95 was required to achieve agreement between the simulated and experimentally measured data.
