Cylindrical Gear

In Gear AT one can define internal and external cylindrical gears, which could be spur and helical gears. In current release you can define a tooth profile from scratch using embedded two step profile generator, i.e. using pre-machining and final machining tool. The first step is to input all gear parameters in the shape definition step of Gear AT preprocessing which stores all geometrical data including profile in a gear property file (*.cgp) which is used as input for meshing and for cylindrical gear element definition. Next step is to generate FE meshes, run Nastran SOL 101 and extract stiffness matrix to a gear stiffness file (*.cgs), which is then used for gear force definition. There are essential geometrical gear data stored in definition file (*.cgd) to define machining tools for later use, so it can be used as input file in Shape Definition dialog box.
