As a rapid calculation of radioactive shield attenuation in truncated cone, the cross points penetrated through the truncated right angle cone shielded region from source points to the detector point have been studied via numerical analysis.
提出一种数值解析法计算从放射线源到评价点的放射线所穿透圆锥台形屏蔽物体的交点坐标 ,从而可快速预测辐射屏蔽衰减率。
A resultant mechanical model for the forming process of cone boss;
锥形凸台体积成形的一种合成力学模型
By analyzing cone bosses forming mechanism in different bulk formations,the forming process of cone bosses was divided into two characteristic time-intervals based on modular design method,one being extrusion processing,and the other being the process of the die corner overflowed by deformable body.
分析了锥形凸台在不同体积成形工艺中的成形机理,基于模块化思想将锥形凸台的成形过程划分为挤压成形与角部充满两个特征时段;将上述两个特征时段的滑移线场力学模型有机联结,构建了锥形凸台成形过程的一种叠加滑移线场力学模型;介绍了叠加滑移线场力学模型的应力场与变形力的求解方法。
