汽车工业中的车轮制造要求车轮无缺陷。然而，工艺和材料缺陷在不同比例的影响一直是生产无缺陷车轮部件的抵消因素。用于轻型和中型商用车的有内胎和无内胎车轮是通过冷成形的切分热轧带由低碳钢制成，具有或不具有微合金化。在带材的制造和成型过程中，轮辋开裂是生产线上的主要问题。本文讨论了轮辋的一种失效形式，即轮辋局部减薄和焊缝处开裂。(C)2007爱思唯尔有限公司保留所有权利。
Manufacturing of wheel in automotive industries demands no-flaw wheels. However, process as well as material deficiency in varying ratios of influence has been the counteracting factors in producing flawless wheel components. Tube and tubeless wheels for light and medium commercial vehicles are manufactured by cold forming of slit hot rolled strips from low carbon steel with or without micro alloying. During manufacturing and forming of the strips, cracking of wheel rims is a major problem at the production line. The paper discusses about one of the failure types in wheel rims, where the wheel rim thins down locally and cracks at the weld. (C) 2007 Elsevier Ltd. All rights reserved.
