冻融作用对黑土坡面融雪、风力和降雨侵蚀的影响研究

Shuitu Baochi Xuebao
[目的] 研究冻融作用对东北黑土区坡面土壤侵蚀的影响,可加深对黑土坡面侵蚀过程机理的认识,并为区域侵蚀治理提供重要科学依据。[方法] 以东北黑土区单一侵蚀营力驱动的融雪、风力和降雨侵蚀为对照,通过设计冻融-融雪、冻融-风力、冻融-降雨双侵蚀营力叠加的模拟试验,分析冻融作用对坡面融雪、风力和降雨侵蚀的影响。试验处理包括1次冻融作用、2个融雪径流量(1,2 L/min)、1个风速(12 m/s),1个降雨强度(100 mm/h)和1个坡度(3°)。[结果] (1)冻融作用显著增加坡面融雪、风力和降雨侵蚀量 ...

多种复合指纹法示踪高寒区流域风水作用产沙来源

Shuitu Baochi Xuebao
目的为运用多种复合指纹法精准示踪高寒区河流、水库等水利设施在风、水复合侵蚀环境下的泥沙来源。方法在黄河龙羊峡水库支流沙沟河流域，采集风沙和水沙泥沙来源区的土壤样本，以及流域出口的新鲜泥沙样本。利用X射线荧光光谱仪测试40种元素指纹因子，采用多组指纹因子法、机器学习最佳复合指纹法、Walling⋅C最佳复合指纹法3种指纹法解析泥沙来源。结果在指纹因子筛选方面，CT-KW-DFA指纹因子筛选方法的DFA累计判别率为82.40%，CT-RF-DFA指纹因子筛选方法DFA累计判别率为100%，CT-RF ...

双动自能式灭弧室静侧传动系统动力学仿真与优化

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 ...
