用于铅带毛坯生产的双辊连铸机,最大瞬间扭矩可达240kN·m。由于主轴结构尺寸的限制,不能将主轴直径设计过大,以致铅带连铸机主轴扭转变形过大的问题一直未能很好地解决。以双辊连铸机主轴直径为设计变量,主轴质量、运行可靠性为优化目标,利用植物生长算法的向光性原理,结合连铸机主轴结构设计问题,通过研究构建了“基于植物生长算法的大扭矩铅带双辊连铸机主轴结构优化设计”数学模型。利用构建的数学模型,对双辊连铸机主轴进行实例优化设计;并通过试验证明了该方法的可行性、科学性和实用性。
For the production of lead billet twin-roll continuous casting machine, the maximum instantaneous torque up to 240kN · m. Due to the size limitation of the spindle structure, the design of the spindle diameter can not be made too large so that the problem that the lead spindle caster torsion deformation is too large has not been solved well. Taking the diameter of main shaft of twin-roll continuous casting machine as the design variable, main shaft quality and operation reliability as the optimization objectives, the principle of directional growth of the continuous casting machine was used to design the spindle structure of the continuous casting machine. Optimization of Design of Spindle Structure for Large Torque Lead-Strip Twin-Roll Caster “” Mathematical Model. By using the mathematical model, the optimal design of the twin-roll continuous casting machine spindle was carried out. The feasibility, scientificness and practicability of the method were proved by experiments.
