摘要
为了解决履带拖拉机车架大梁的断裂问题 ,对车架大梁进行了残余应力测试及振动时效试验 ,并对振动时效前后的残余应力分布进行了比较。试验结果表明 ,车架大梁的断裂与残余应力太高有关 。
Residual stresses in tractor frame beam before and after vibratory stress relief were tested for understanding of beam fracture. The results showed that beam fracture was resulted from high residual stress, and vibratory stress relief could greatly reduce residual stress and improve the stress distribution mode.
