drag formula
Examples
- In this thesis , the technology of visual fictitous design was used to design the level exchanged direction and double direction plough . first , the traction force formula of cylindrical plough face based on the prior study was deduced , and the forces of the solid model of circumrotatory pin was calculated , and visual dummy design technology was applied to analyse the force of circumrotatory pin and the parameter of pin
其次在前人研究的基础上推导出圆柱型犁体曲面的牵引阻力公式；根据该公式计算出旋转销三维实体模型所受的力，根据该力运用可视化虚拟设计技术对模型进行受力分析，对旋转销的参数进行合理设计；根据牵引阻力公式计算出安全螺栓所受的力，根据该力运用虚拟设计技术对安全机构进行设计。 - Therefore , based on the resistance formulae which is obtained at the beginning of this paper , the mathematic model which sets the economic value as the objective function can be established , and then uses optimization method to get the best structure of the filter when its first invest , maintenance together with operating costs are most economical . and the different results gaining from resistance and economic analysis are compared at the end
因此本文最后着重在经实验最终确立的阻力公式基础上，以多管式高效过滤器的经济性指标为目标函数建立数学模型，采用有约束单目标多变量的最优化方法，计算得出了该种过滤器初投资和运行维护的费用总经济性最优时的结构参数，并与仅从阻力方面考虑所得到的结果进行了分析比较。
