【摘要】 为了研究水力驱动控制棒系统应用于HR-200的工作情况、影响性能的因素及改进措施,采用微偏法和分段法对二阶级性微分方程组进行了合理的线性化处理,然后用拉普拉斯数学变换进行求解,得出了控制棒在平衡点附近的运动规律和任意位置时的简单数值解法,进行了理论上的计算分析,并用实验进行了比较验证。从计算结果和实验结果可知:把水力驱动控制棒系统进行适当的结构改善和参数变化应用于HR-200后,具有良好的各态性能。在此基础上,研究了各态下影响系统特性的主要因素及改善措施。更多还原

【Abstract】 In order to analyse the performance on the Hydraulic Control Rod Driving System for HR-200 Heating Reactor, factors affecfing its performance and some possible improvements on this system, a methed is presented, that is,first linearize the two-order nonlinear differential equations by neglecting the multi-powered small quantities or segmenting , then solve the linearized differential equations using Laplace transformation. The motion rule of the control rod near the ballance position is found and a simple numerical method to calculate the rod’s movement on any position is proposed. A theoretical analyses and comparisons with experimental results are conducted. Both the theoretical analyses and the experiments show that with certain structural improvements and parameters change, this Hydraulic Control Rod Driving System will be able to work properly on HR-200. Further,the main factors affecting the system’s performance are analyzed and some reasonable improving methods are proposed.更多还原
