针对悬臂轴拉杆在自由端受集中力问题进行了随机分析,其中考虑了轴拉杆杨氏模量的变异,在小变异情况下获得了不同相关结构与相关长度下问题的解析解,并就结果对相关结构的敏感性进行了讨论。 Aiming at the fact that the free end of the cantilever shaft rod is subjected to a concentrated force problem, a stochastic analysis is carried out, in which the variation of the Young’s modulus of the shaft rod is taken into account and the analytic solution of the problem under different related structures and relevant lengths is obtained under the condition of small variation. The sensitivity of the related structures was discussed.
