| 摘 要： | 钢丝绳在矿井实际工作中绳股中的实际载荷并不明确,而实际工作载荷对工作的安全性至关重要。通过对6×7IWS同向捻钢丝绳进行理论分析,在有限元分析软件中建立空间结构和尺寸均与实际相符的模型;在进行相应的网格划分后,设定相关参数;选择现场常见的工况设定相应的边界条件,即钢丝绳一端约束所有自由度,另一端施加载荷进行仿真计算。为了明确摩擦力对计算结果的影响将计算分成2组,一组采用忽略摩擦力存在的情况,对照组采用考虑摩擦力的情形且根据实际工况中测定的摩擦因数进行赋值计算。结果表明,如忽略摩擦力进行分析,所得数据与实际工况相差较大,因此对于实际工况中的仿真计算不易采用忽略摩擦的简化计算方法。

| Abstract: | In the mine actual operation,the actual load of the steel tope strands in the steel rope would be uncertain,but the actual working load would be critical to the safety of the work.With the theoretical analysis on the 6X7IWS same directional stranding steel rope,a model with the space structure and size fully fitted to the actual related established in the finite element software.After the related net divided,the related parameters were set up.The site comment performances were selected to set up the related... |
