Abstract

Taking into account high requirements to the operation conditions of precision machines, the study of strength deformations of carrying systems is a rather critical task. The paper presents the methodology of analysis of strength deformations of the machines carrying systems when moving the substantial movable bodies of manufacturing systems during contact interactions of surfaces using the finite element method. The authors selected 2A459SF4 precision horizontal multi-axis boring machine (HMBM) as an object of study. The authors developed a 3-D model of a machine taking into account the joint of fixedly connected parts with movable machine parts. The study was carried out using the ANSYS Workbench 14.5 software complex. The paper presents the accessible assumptions that were taken into account when calculating strength deformations during contact interactions. The authors give the detailed description of configurable settings of contact interactions within the design model in the ANSYS Workbench 14.5 software complex. The authors carried out the static calculation of strength deformations of carrying system of precision HMBM during contact interactions with the further calculation data entry into the tables. During calculation, the discrete movement of the machine column occurred. The calculation was carried out at three positions of the machine column: the most remote from the processed workpiece, central position and during the workpiece processing. It was done to consider the influence of column position on total strength deformations of the machine frame and the strength deformations in the joints during contact interactions. The paper presents the comparative analysis of control points movement during theoretical and experimental studies. The authors proved the adequacy of this methodology of analysis of the machine carrying systems strength deformations during contact interaction of surfaces.
