合理地采用牢固、耐用、省料的车厢底座设计.是制造重型载重汽车的重要课题。这种被称之为优化的工作完全运用于三面翻自卸车车厢底座的设计上。所谓优化设计是通过对应力状态、材料的几何及强度特性.底座的基本结构和支点坐标的计算而实现的。在设计中可以把构件的尺寸、提 Reasonable use of solid, durable, material-saving car base design is an important issue in the manufacture of heavy duty trucks. This is called the optimization of the work fully used in the design of the base of the dump truck body. The so-called optimal design is through the stress state, the geometry and strength of the material properties of the basic structure of the base and fulcrum coordinates calculated and achieved. In the design can be the size of components, mention
