道路清障车工作装置的强度分析

在对道路清障车工作装置进行受力分析的基础上．绘制了工作装置在危险工况的弯矩图、剪力图及轴力图，并对工作装置和销轴分别进行了强度校核。用实例说明了工作装置截面的选择和确定植物直径的方法，提出了结构布置建议。

On the basis of stress analysis for the road-block removal truck working device,its bending moment diagram and shear diagram and axial force diagram were drawn when it is in risky operating mode; The intensty proof was carried out respectively for the working device and its jointed shafts. Besides, methods of the selecting working device cross section and the definiting diameter of jointed shafts were explained by example; A proposal concerning structure of the working device was put forward.
