Study of the Strength Characteristics of the Support Frame of Horizontal Roller Mill in NX CAE

Abstract

The grinding process is one of the main ones in the manufacture of many building materials, such as cement, limestone, gypsum, etc. The design of equipment and machinery for the construction materials industry is intimately associated with the implementation of many types of computations. This paper describes the computation stages to find out the strength characteristics of the support frame of a horizontal roller mill using the finite element method implemented in the CAD/CAM/CAE NX system. The “Advanced Simulation” module of the NX system allows evaluating how the electronic-digital model of the product will act in real use. The collection of loads for analysis, the preparation of the geometry of the electronic-digital model of the support frame of the mill, the generation of finite element grids and the setting of physical and mechanical properties of materials, and the imposition of boundary conditions are considered. Multiple conducting and analysis of preliminary computations using the NX Nastran solver gives the chance to make changes to the design of the support frame quickly and efficiently (the master model principle) to meet the requirements of strength and stiffness of each part of the assembly. This approach to conducting finite element analysis allows correcting the civil engineer’s idea, optimizing the amount of material expended on manufacturing, and ensuring the service reliability of the projected product design without attraction of large costs for test trials.
