目的:根据神经网络算法和线性回归分析算法,建立基于轴向游隙贡献量的一种套圈零件智能匹配模型。方法:首先利用神经网络算法研究轴承沟道游隙变量与套圈零件的沟道游隙之间多对多的函数映射关系,建立输入元、输出元和中层处理层,建立数据库和阙值函数为学习细胞元;其次,通过线性回归计算出大量不同尺寸的套圈零件和钢珠函数的斜率,建立线性函数模型;最后建立基于轴向游隙贡献量的整体匹配模型。结果:以某轮毂轴承生产厂商作为案例验证模型,对数据进行蒙特卡洛仿真,得出该厂商生产的零件尺寸服从标准正态分布和左偏0.1正态分布的情况下,匹配合套率达到97%。结论:证明建立的模型有效,满足该厂商的生产要求。
Abstract：Aims: According to neural network algorithms and linear regression analysis algorithms, an intelligent matching model of ring parts was established based on axial clearance contribution. Methods: Firstly, the neural network algorithm was used to research the multi-to-multi function mapping relationship between the bearing channel clearance variables and the channel clearances of the ring parts. The input elements, output elements and middle processing layers were established. The database and threshold function were set up as learn cell elements. Secondly, linear regression was used to calculate the slope between a large number of different sizes of the ring parts and the steel ball function, and the linear function model was built. Finally, an overall matching model was established based on axial clearance contribution. Results: By taking the manufacturer of a hub bearing as a case to verify the model, Monte Carlo simulation was carried out on the data. The results showed that the rate of matching appropriate reached 97% when the size of the parts manufactured by the manufacturer obeyed the standard normal distribution and the left deviation 0.1 normal distribution. Conclusions: The model meets the manufacturer's production requirements and is proved to be effective.
