Simulation / Computer Aided Engineering (CAE)

The technology used to simulate physical phenomena and conduct numerical analysis on a computer has become increasingly important for determining the basis of design without making an actual item. Xerography (electrophotography) is a system that involves multiple physical phenomena such as exposure, friction charging, and phenomena in granular materials that interact with each other. Given the difficulty of conducting numerical analysis of these complex phenomena by using conventional simulation analysis technologies, Fuji Xerox developed its own dedicated simulator. With this simulator, we can check the parameters for xerographic processes from an early stage of design. As a result, we succeeded in shortening the development period.

We also created templates, or simplified parts models. As the basic functions of parts can be evaluated through simulations using these templates, even people without advanced simulation skills can easily conduct analysis. Even before CAD data are completed, it is possible to study various cases by simply entering the dimensions of parts and other parameters. Therefore, we can determine highly robustNote1 design parameters at an early stage of design by combining the use of CAE tools and quality engineering methods.

We also use various CAE tools that are 3D CAD modules (for configuration, mechanism, vibration, heat conduction, thermo-fluid dynamics) to simulate phenomena and motions related to complex structures, and clarify the basis of design during the "virtual" phase before building actual items.
