In the work, on the basis of the analysis of publications, existing approaches to the numerical modeling of additive processes of product formation are shown. The work itself is devoted to the study of the influence of parameters of the process of surfacing wire materials on the formation of residual deformations in parts. A mathematical formulation of the non-stationary thermomechanical problem is presented, and algorithms for solving the problem using the technology of birth and death of finite elements in the ANSYS package are described. Verification of the model created by the finite element was carried out on the basis of data from the experiment on surfacing a multilayer sample. The effect on the level of residual warping of the following process parameters was studied: the exposure time before the next layer was deposited; the motion path of the burner; ambient temperature. It is shown that the change in ambient temperature is the most effective way to reduce the residual distortions of the form.

导线沉积过程的3D数值模拟以预测零件的变形

在工作中，在分析出版物的基础上，展示了现有的产品形成附加过程数值模型的方法。这项工作本身致力于研究线材堆焊工艺参数对零件残余变形形成的影响。提出了非平稳热力学问题的数学公式，并描述了使用ANSYS软件包中的有限元生死技术解决问题的算法。有限元创建的模型的验证是基于表面多层样品的实验数据进行的。研究了以下工艺参数对残余翘曲程度的影响：沉积下一层之前的曝光时间；燃烧器的运动路径；环境温度。结果表明，环境温度的变化是减少模板残留变形的最有效方法。
