针对108t电动轮矿用自卸车车架的局部开裂现象，通过有限元分析及强度测试，对应力集中部位进行了结构改样，使车架的应力降低30％左右．为车架的设计提供了依据。
Aiming at the local cracking phenomenon of 108t electric wheel dump truck frame, the stress concentration area is reformed by finite element analysis and strength test, the stress of frame is reduced about 30%. For the design of the frame provided the basis.
