一种齿轮副模型及其在多体动力学仿真中的应用

为了建立基于优秀的多体动力学仿真软件(ADAMS)的齿轮传动系统虚拟样机模型，对传统的齿轮副扭转振动模型进行动力学等价变换，推导出一种齿轮副传动模型。该齿轮副模型包含传统齿轮副扭转振动模型的全部动力学内容，能在ADAMS中方便定义，应用广泛。利用该齿轮副模型建立的齿轮系统模型能直接进行系统扭转振动固有特性、频域特性、考虑多种激励的动态响应等方面的仿真。

A GEAR PAIR MODEL AND ITS APPLICATION IN THE SOFTWARE ADAMS

To set up the virtual prototype of a gear train system in the dynamic analysis software ADAMS, the torsional vibration model of the gear pair is transformed into an equivalent kinetic model viz. the transmission model. The model includes all the kinetic contents of a torsional vibration model, and can be defined easily and widely applied in ADAMS. Gear train systems built on this transmission model can be used to calculate for their inherent torsion characteristics, frequency characteristics,dynamic response,etc.
