本文是文献的继续。本文用等参有限元法,进一步研究了剩余打击能量对棋腔底部内圆角应力场的影响。结果表明,从静强度的观点来看,在有剩余打击能量作用时,内圆角下危险点的危险程度有所减小。但是,从另一方面来看,有剩余打击能量比没有剩余打击能量时,锒块内部的应力梯度更大,即应力分布更加不均匀。这后一点将导致锻模易于脆断,从而增大了产生脆性断裂的危险性。 This article is the continuation of the literature. In this paper, using isoparametric finite element method to further study the residual impact energy on the bottom of the chess at the bottom of the fillet stress field. The results show that from the point of view of static strength, the danger level of the dangerous point under the fillet is reduced when there is residual impact energy. However, on the other hand, there is a greater stress gradient inside the slab when there is residual impact energy than there is no residual impact energy, ie, the stress distribution is more uneven. This latter point will result in the forging being prone to brittle fracture, increasing the risk of brittle fracture.
