摘　　要：介绍了热成型技术在车身开发中的研究与应用情况。以某车型后纵梁和B柱加强板为例,借助Auto Form软件,分析加热温度、加热时间、成型速度、冷却速度等工艺参数对热成形过程的影响,避免热成型模具因冷却水道布置而更改不易的问题,同时根据热成型零件的加工特点,提出了一系列有效措施来降低热成型零件的成本。Research and application of hot forming technology is introduced in the body de- sign. Taking a rear longitude beam and B post reinforcement panel as an example, with the help of Au- to form software, the influence of heating temperature, heating time, the speed of forming process pa- rameters, the cooling speed of hot forming process is analyzed to avoid that the hot mold for cooling channel layout change is difficult. At the same time, according to the processing characteristics of hot forming parts, a series of effective measures to reduce the heat forming part of the cost are put forward.
