摘　　要：利用ANSYS软件为工具,引入接触非线性有限元法,对吊臂整体进行接触分析,并绘制出滑块支撑处的局部应力云图。在此基础上,就滑块支撑处局部最大应力进行优化设计,得出了滑块支撑的最佳位置,能有效地降低滑块承受的应力。Using ANSYS software as a tool and applying the contact nonlinear finite element method, this essay conducts a contact analysis of the jib as a whole and plots a local stress cloud diagram for the points at which the jib sliding blocks are supported. On the basis of this, the essay further carries out an optimization design of the maximum local stress around those supporting points and thereby obtains the optimum positions for supporting the sliding blocks, which in turn enables a substantial reduction in the stress borne by the sliding blocks.
