摘要
研究了矿井提升机井架结构优化设计问题。以井架结构重量为目标函数,应力和节点位移为约束条件,通过APDL语言建立了井架优化的数学模型,并采用一阶方法对优化模型进行求解。分析结果表明,井架结构重量显著降低,仅相当于优化前重量的25%。
The problem of optimization design of the mine hoist derrick structure is investigated. By setting the derrick structure weight, the stress and nodes displacement as objective function and constrains respectively, the optimization model of the derrick is constructed by using the APDL language, and solved by employing the first-order method. The results showed a significant reduction in the weight of the derrick structure, in which equivalent to 25% of the weight before optimization.
