|
摘要
为提高盘形滚刀破岩性能与使用寿命,基于滚刀刀圈结构设计要求与原则,提出一种滚刀刀圈结构地质适应性设计方法。以滚刀破岩能力、破岩能耗、轴承受载以及磨损性能为优化目标,建立滚刀刀圈结构多目标优化设计模型。采用模糊层次分析法计算不同地质条件下目标函数权重值,并通过遗传算法对模型进行求解。将滚刀刀圈结构地质适应性设计方法应用于某供水工程TBM项目滚刀优化设计,结果表明:不同地质条件下刀圈结构参数设计需要具有针对性,滚刀刀圈优化设计方法通过专家评判合理设置优化目标权重系数可实现刀圈结构地质适应性设计与选型,有效提高了滚刀破岩性能与使用寿命。
To improve the rock-breaking performance and service life of the disc cutter, a geological adaptability design method of structural parameters for the disc cutter ring is presented based on the design requirements and principles of the disc cutter ring. A multi objective optimization model of structural parameters for disc cutter ring is established by taking the rock-breaking ability, specific energy, loading of the bearing and wear performance of disc cutter as optimal objectives. The fuzzy analytic hierarchy process is applied to obtain the weights of the objective functions under different geological conditions, and the genetic algorithm is employed to solve the optimization model. A case application is offered to illustrate the proposed method. The results show that the structure of the cutter ring should be designed according to the specific geological conditions. By setting the weights of objective functions reasonably on the basis of the expert investigation approach and fuzzy analytic hierarchy process, the optimum design method of disc cutter ring is feasible to geological adaptability design and selection for disc cutter ring which can effectively improve rock-breaking performance and service life of the disc cutter.
