Practical Examples and Future Directions for CAE-Based Development for Automobile Transmissions by Designers

Article of Honda R&D Technical Review Vol.15 No.1


Three-dimensional (3D) CAD systems have been used for design and development of automobile transmissions for several years. These systems have been improved to the point that they can be used to design sand castings which have precision equivalent to that mass-produced from die molds. Since automatic meshers for CAE analysis have improved so much, it has become increasingly common practice for designers to use, as is, the 3D models of prototype parts and mass products in CAE analyses to make decisions on the detailed specifications of components. The next step in this revision of CAE systems is to re-create them as a more designer-friendly environment, and allow designers to use these systems to perform CAE analyses not only of individual components, but also of assemblies, a much more difficult task.
