本文在概要阐述螺旋滚筒结构及主要参数的基础上,用优化设计的方法,提出了小直径螺旋滚筒参数优化设计的数学模型,并选择了SUMT内点惩罚函数法。通过实例计算,其结果是令人满意的。目前,在薄煤层采煤机小直径螺旋滚筒的设计上,面临的突出问题是,如何保证滚筒既具有良好的截割性能,又具有理想的装煤能力。对此,本文采用优化设计的方法,对小直径螺旋滚筒主要参数进行了初步地探讨,以供有关同志参考。 In this paper, based on an overview of the structure and the main parameters of the spiral drum, a mathematical model of the optimal design of the parameters of the small-diameter spiral drum is proposed with the method of optimal design. The penalty function of SUMT is chosen. The result of the calculation is satisfactory. At present, the design of small-diameter shearer in the thin coal seam shearer, the prominent problem is how to ensure that the drum has both good cutting performance, but also has the ideal capacity of coal loading. In this regard, this paper uses the method of optimal design, the primary parameters of a small diameter spiral drum was initially discussed for reference by the relevant comrades.
