摘要： 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.
摘要翻译：为了处理接触式建模中的轻型和其他齿轮变形，齿轮的顺从性得到了改进。由于接触引起的齿轮齿的顺应性分为大量和局部接触顺应性。批量合规性会考虑网络版本，并预先计算以减少模拟期间的处理时间。局部顺应性被准静态地处理，以限制模拟期间的时间积分。模拟中包括一个或多个其他可能的特征，例如计算由一个齿轮与多个物体的接触导致的柔量，而不是仅仅一对齿轮，忽略刚性齿轮的顺应性，考虑到连续的齿对之间的耦合，而不需要散装模拟中的顺应性计算，考虑到齿轮空白几何，考虑到齿轮弹性的动态响应，假设只有一部分齿轮主体顺应性反应准静态，并为齿轮建立非轮形形状。

摘要： In order to decrease computation requirements for updating ease-off for simulated mating gears upon changed misalignment and calculating corresponding gear penetration, the effect of gear misalignment is linearized. At least one representation of misalignment is added to an initially calculated ease-off to update the ease-off in response to the misalignment. The at least one representation of misalignment includes a representation of relative translation misalignment between the gears, a representation of relative rotational misalignment between the gears, a relative approach between gear flanks at a contact point, or a combination thereof.
摘要翻译：为了减少更换不对准时计算模拟匹配齿轮的计算要求，并计算相应的齿轮穿透，齿轮未对准的影响是线性化的。将未对准的至少一个表示添加到初始计算的容易程度以响应于未对准来更新缓解。至少一个不对准的表示包括齿轮之间的相对平移不对准的表示，齿轮之间的相对旋转未对准的表示，接触点处的齿轮侧面之间的相对接近或其组合。
