Sheet Metal Rack Design and Development Using Static, Modal, and Seismic Analysis

Abstract

Sheet metal racks are essential for housing electronic modules and equipment. This paper discusses the design and analysis of a sheet metal rack subjected to static, dynamic, and seismic loads. The design process focuses on optimal geometric dimensions, material selection, and boundary conditions, leading to a recommended safety factor. Static and modal finite element analysis (FEA) were used to assess deformation at critical points and to capture the mode shapes associated with the operational frequency range. Seismic analysis provided insights into the structural loads and moments critical to the rack's performance at lower operating frequencies. This study outlines a comprehensive design process for finalizing the geometric dimensions of sheet metal modular racks, applicable to various storage needs.
