摘要:
为提高采煤机截割部末级行星机构的承载能力,选择齿轮、模数及变位系数等7个主要参数作为设计变量,在传动比、重合度约束等11个不等式和3个等式约束的条件下,建立以行星齿轮弯曲应力和总体积为目标函数的优化模型。考虑行星机构优化模型的多峰特性,采用烟花算法进行求解,引入Sigmoid函数构建自适应爆炸半径和学习算子改进烟花算法,通过6种典型测试函数进行标准测试和偏移测试。结果表明:改进型烟花算法表现出较好的寻优能力和稳健性; 优化后,总体积降低0.95%,太阳轮弯曲应力为302 MPa,行星轮弯曲应力为299 MPa,内齿圈弯曲应力为224 MPa,分别减少15.9%、15.8%和16.7%。
Abstract:
This paper seeks to improve the bearing capacity of the final planetary mechanism of the cutting section of the shearer. The improvement is achieved by developing an optimization model with the bending stress and total volume of planetary gear as objective functions by selecting as design variables 7 main parameters, such as gear, module and displacement coefficient, under 11 inequality constraints such as transmission ratio and overlap degree constraints and 3 equation constraints. The study includes solving the problem by considering the multi-peak characteristics of the planetary mechanism optimization model and using the spark algorithm; constructing the adaptive explosion radius and learning operator by introducing the Sigmoid function to improve the spark algorithm; and performing standard tests and offset tests using six typical test functions. The results show that the improved firework algorithm features a better optimization ability and robustness; and the optimization is followed by a 0.95% reduction in the total volume, with a 15.9%, 15.8% and 16.7% reduction respectively for the bending stress of solar wheel(302 MPa), the bending stress of planetary wheel(299 MPa), and the bending stress of inner ring gear(224 MPa).
