Abstract
To deal with lightweight and other gear modification in contact modeling, the compliance of the gear is refined for the simulation. The compliance of the teeth of the gear due to contact is separated into bulk and local contact compliance. The bulk compliance accounts for the web variation and is pre-calculated to reduce processing time during simulation. The local compliance is treated quasi-statically to limit time integration during the simulation. One or more of other possible features are included in the simulation, such as calculating compliance resulting from contact of one gear with multiple objects instead of just one pair of gears, neglecting compliance of a stiff gears, accounting for coupling between successive teeth pairs without bulk compliance calculation in the simulation, accounting for gear blank geometry, accounting for a dynamic response of the gear flexibility by assuming that only a part of the gear bulk compliance responds quasi-statically, and modeling non-wheel like shapes for the gear.
