Shuitu Baochi Xuebao[目的] 为探明磷素对含沙水流流体变异特性的影响。[方法] 采用自制双竖管流变仪,研究了磷素对不同浓度含沙水流流体类型、流变参数及流体发生变异的临界阈值的影响。[结果] (1)磷素浓度、泥沙浓度及泥沙理化性质是影响含沙水流发生流体变异的主要因素。在25 ℃下,过磷酸钙浓度每增加0.1 g/cm3,黏滞系数和宾汉极限剪切力分别增加0.48~1.47 mPa·s和3.49~6.84 N/m2。(2)随着磷素和泥沙含量的增大,含磷素的含沙水流由牛顿流体变异为宾汉流体。构建并验证了磷 ...

Gaoya dianqi在高压断路器分闸与合闸过程中，静侧传动系统的强度直接影响产品的机械寿命，550 kV断路器与以往的产品相比，提高了电压等级，意味着更难满足机械寿命要求，因此需要更加准确地预测和提高静侧传动系统的结构强度以保证寿命要求。文中建立了双动自能式灭弧室静侧传动系统的柔性瞬态动力学模型，该模型基于Hypermesh进行前处理，并利用Ls-dyna进行了瞬态动力学仿真求解。在分析过程中运用了显示算法，充分考虑了网格类型、接触类型、间隙、碰撞冲击等因素的影响。应力仿真结果表明：不同速度工况下 ...
