摘要 随着蓝海战略提出,内燃机向更大规格发展,作为内燃机关键部件之一的气门就有着更高精度、更高耐腐蚀性、耐冲击的要求,气门电热镦成形工艺参数优化成为了气门电热镦生产亟待解决的问题。本文总结了气门电热镦粗成形工艺过程属于难于控制的多场耦合过程,国内外目前没有可参考的气门电热镦聚料工艺的多场耦合模型的研究现状。本文综述了采用电-热-结构多场动态耦合仿真技术研究,可以有效控制工艺参数对电热镦件晶粒度及晶粒分布不均匀度的影响规律,优化气门电热镦粗成形工艺,并己取得实际应用。 The electro-thermal-structure multi-field dynamic coupling simulation technology has been studied in the text, which can effectively control the influence of process parameters on the grain size and grain distribution unevenness of electric thermal elements. The electrical thermal upsetting process for the valve has been optimized and put into the actual application.
