Abstract

The quality of aircraft and rocket engines depends primarily on the geometric accuracy of assembly units and parts. Mathematical models implemented in the form of computer models are used to predict quality indicators (in particular, assembly parameters). Direct modeling of the conjugation process using numerical conjugation and finite-element models of assemblies requires significant computational resources and is often accompanied by problems convergence of solutions. In order to solve the above problems, it is possible to use neural network models describing the main regularities of the pairing process based on the accumulated results. The work presents a neural network model for predicting assembly parameters of the parts based on the use of actual surfaces of the parts obtained as a result of mathematical modeling. Assembly on conical surfaces is considered. A convolutional neural network was used to predict assembly parameters.
航空发动机零件相对位置几何参数数字预测中的神经网络模型
飞机和火箭发动机的质量主要取决于装配单元和部件的几何精度。以计算机模型形式实现的数学模型用于预测质量指标(特别是装配参数)。用数值共轭和装配体有限元模型直接模拟共轭过程需要大量的计算资源,并且常常伴随着解的收敛性问题。为了解决上述问题,可以利用基于累积结果的神经网络模型来描述配对过程的主要规律。本文提出了一种基于零件实际表面的神经网络模型,用于预测零件的装配参数。考虑了圆锥表面上的装配。采用卷积神经网络对装配参数进行预测。
