电动轮矿用车电控柜安装支架有限元分析

利用有限元软件ANSYS Workbench,对电控系统安装支架进行几何处理与网格划分,建立相应有限元模型。结合矿用车典型的作业工况,研究安装支架在垂直冲击、转弯、加速、制动工况下的连接结构强度,同时分析其在约束状态下的模态频率。结果表明,在4种典型作业工况下,该电控系统支架结构合理,能满足强度要求,振动模态特性也符合矿用车日常使用需求,可以为同类产品的设计优化提供参考。

Control strategy for multi-pump emulsion power station in coal mine face

Shearer and hydraulic support are matching equipments. To increase the operating speed of the shearer, the following speed of hydraulic support must be increased. This means increasing the volume of flow from emulsion power station. Analyzing the operating characteristics of hydraulic supports, the number of simultaneously operating supports is obtained by means of pressure parameter and time history at a certain time, which is a theory base for development of control system to multi-pump emulsion power station.
