Finite Element Analysis

The rapid advance of Computer Aided Engineering (CAE) techniques and software have lead to a virtual revolution in companies that continue to invest in the latest in high-speed computers and computational software for analyzing parts and assemblies. One of the most important components of CAE that Northwood uses is Finite Element Analysis (FEA), a detailed mathematical computer simulation that enables engineers and designers to develop products more quickly and completely that traditional prototyping methods allowed. FEA makes it possible for specific machine components to be targeted for in-depth analysis to eliminate failure from fatigue rather than waiting for those components to begin failing (sometimes years into a product's lifecycle).

FEA tools also provide visual verification of both the element meshing (for integrated calculations) and for the locations of resulting data for large, complex structures or for small, single parts. In this process, geometries are broken down into elements, and each element is meshed, with each mesh connecting at points called nodes according to various model parameters and analysis type. The byproduct is an accurate simulation and prediction of various physical effects such as stress, strain, deformation, vibration, etc. This means that you can expect your Northwood machine to be rigid, quiet, strong, and long lasting. Combined with good result estimation practices and error checking, FEA is an invaluable tool for the modern manufacturer.
