摘要:

为优选缫丝机卷绕机构结构参数,首先建立不同类型非圆齿轮副驱动的卷绕机构通用运动学数学模型。进一步以生丝卷装断面的理想几何特征为目标函数,建立了通用参数优化数学模型,再通过遗传算法求解满足生丝卷绕工艺的非圆齿轮节曲线参数。选取其中的巴斯噶蜗线型卷绕机构模型为例,进行参数优化、试验台研制及生丝卷绕试验。非圆齿轮副驱动的卷绕机构试验得到的卷装断面廓线与理论计算廓线基本吻合,验证了通用数学模型的正确性,且成形的卷装表面平整度较高、平整段较宽,验证了所设计的卷绕装置在实际作业中的可行性及优越性。

Abstract:

In order to optimize the structural parameters of winding motion mechanism. Firstly, general kinematics mathematical models of winding motion mechanism driven by different types non-circular gears was established. Further, taking the ideal geometric characteristics of raw silk package profile curve as objective function, a general parameter optimization mathematical model was established, and then the pitch curve parameters of non-circular gears satisfying raw silk winding technique were solved by genetic algorithm. The winding motion mechanism driven by hybrid order Pascal curve non-circular gear pair was selected as an example to optimize the parameters, the test bench was developed and the raw silk winding experiment was carried out. The profile of winding mechanism driven by non-circular gear pairs basically coincides with the theoretical calculation profile, which verifies the correctness of the general mathematical model. Moreover, the package surface has a high planeness and a wide flattening area, which verifies the feasibility and superiority of the winding mechanism designed in the actual silk winding operation.

Key words: winding motion, non-circular gear, parameter optimization, silk reeling machine
