U型钢三心拱支架的优化设计

The optimization design of U-steel metal yielding three-centered support

简述了影响三心拱支架架型选择的地质因素和国内各矿支架设计所存在的问题,并在已知三心拱支架架型和保证支架良好的承载能力的基础上,考虑三心拱顶弧所对的弧圆心角和其半径同时变化的前提下,编制了计算机程序,并用其对三心拱支架的搭接进行了优化设计,计算过程具有动态优化效果,计算结果精确合理,从而验证了程序的可靠性,解决了材料的不必要浪费问题。

Have a brief statement on the geology factor which effects the choosing of three-centred support and the problems exist in local mine in selection of the support.Assumption knowing the style and ensuring the good bearing capability of three-centred support,a computer code is built.The changing of central angle and semi-diameter is under consideration in the computer code,which determines the support's bearing capability,so the process of loop computing has the dynamical optimization effect.The precise results are the certification of computer code and the problem of extravagant is solved under the code.
