对起重运输机械常用的拉杆进行设计校核时经常只考虑轴力的影响而忽略了弯矩的影响，使设计存在安全隐患。文中列举了两种计算拉杆弯矩的方法，并考虑了轴力对弯矩的影响。比较了不同方法在计算校核拉杆强度时的误差，为设计安全合理的拉杆截面提供理论支持。

Design calibration of the pull rod commonly used in hoisting machinery generally involves only the effect of the axial force without regard of the bending moment,resulting in potential safety hazards.The paper introduces two meth-ods for calculating the pull rod bending moment,with the effect of axial force on the bending moment considered.Different methods are compared in respect of calculating and calibrating the strength of the pull rod,providing theoretic support for designing secure and proper pull rod section.
