摘　　要：针对HR 2 0 0MW槽孔式水力驱动控制棒槽对孔处的阻力系数 ,在总结阻力系数经验公式的基础上 ,建立计算模型 ,推导出阻力系数公式 ,并进行了理论分析。分析结果表明 :阻力系数随槽与孔重合面积的增大而减小 ;步进缸内孔越大 ,阻力系数越小 ,但内孔增大到一定的值后 ,阻力系数趋近于某一个定值。为HR 2 0The resistance coefficient on new type Hydraulic Driving Control Rod of chamfer and orifice type for HR 200 MW is discussed. According to empirical equations, the calculation model has been built, and the resistance coefficient formula is derived, then the theoretical analysis is carried out. The results show: The greater the internal hole area is, the less resistance coefficient is, and it tends to a certain value, and so is the superposition area between the chamfer and the orifice. It laid the foundation of theoretical analysis for the engineering design of HR 200 MW.
