机械CAD是当代最先进的设计手段。液力变矩器叶轮的形状和受力状况都很复杂,传统的设计方法很难精确计算其强度,难免造成材料的浪费。采用CAD系统中的实体造型,图形有限元,有限元分析等软件包及其编辑器,可以构造出变矩器叶轮并计算出其应力和变形。这就为节约原材料提供了有效的手段。CAD系统的功能广泛,是从经验设计过渡到科学设计的必由之路。 Mechanical CAD is the most advanced contemporary design tool. Torque converter impeller shape and stress conditions are complex, the traditional design method is difficult to accurately calculate the strength, inevitably lead to waste of materials. Using the CAD system of solid modeling, finite element graphics, finite element analysis packages and editors, you can construct the torque converter impeller and calculate the stress and deformation. This provides an effective means of saving raw materials. The wide range of functions of CAD system is the only way to make the transition from experience design to scientific design.
