凹梁式车辆运输半挂车的设计

Design of concave beam type semitrailer of vehicular traffic

介绍了东风汽车公司重型车厂开发设计的 30 t凹梁式车辆运输半挂车的结构特点及设计方案。运用计算机语言编程对纵梁进行了电算化受力分析、应力计算，为新产品设计提供了一种新思路。

30－ton concave beam type semitrailers of vehicular traffic,developed by DFM heavy vehicle factory,are introduced including the structure feature and design plan.By editing computer programming,a new design method for electric calculating force analysis and stress calculation of the side members is carried out.
