Utilizing the 3D modeling technology to design a welding fixture

Abstract

The article discusses utilizing the 3D modeling technology to design a welding fixture for the mechanical engineering industry. To improve the efficiency of the design process, we used the NX computer-aided design (CAD) system as a design tool. We describe the process of developing 3D models for individual components of a welding fixture with the said system. The possibilities of utilizing the created 3D model to analyze the finished product in kinematics by means of the NX system are considered. An algorithm to compute the parameters of the welding fixture using the finite element analysis (FEA) is described. As evidenced from practice, utilizing the 3D modeling technology allows design engineers to significantly reduce the time spent on a welding fixture design and implementation at a machine-building enterprise.
