摘　　要：通过对常见开口截面车架在典型工况时扭转应力的分析,推导出扭转应力计算公式,从而得出了开口截面车架的一些应力分布规律,提出了改善车架扭转应力分布的具体措施.对汽车车架设计方案的拟定和车架应力分析具有指导作用.Through the analysis of the torsional stress produced in the open sections vehicle frames under typical operation conditions the calculating formula is achieveal, which leads to the stress distribution of the open section frame and the ideas of improving the distribution of the torsional stress are discussed. It＇s a significant guidance for determining the scheme of frame designing and stress analysis.
