摘　　要：针对U型钢支架轴向应力分布规律问题,采用Patran数值计算软件,建立了支架轴向应力数值模型,分析了不同截面型号的U型钢支架的轴向应力分布规律。结果表明,U型钢支架不同位置处,轴向应力远大于剪切应力,且轴向应力与Mises应力几乎相等,可以采用轴向应力替代Mises应力校核支架的强度。By Patrannumerical calculation software,the numerical model of axial stress of U-shaped steel support was established.The axial stress distribution of U-shaped steel support with different section types was analyzed.The results showed that the axial stress was much greater than the shear stress at different positions of the U-shaped steel support,so the axial stress basically equal to Mises stress.The axial stress can be used instead of Mises stress to check the strength of the support.
