圆柱型犁体 meaning in English

cylindrical bottom

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。
