ボンドグラフによるトルクコンバータの動特性解析

抄録

From the standpoint of power conservation, bondgraphs can represent various systems by a unified approach., even which are composed of mechanical, hydraulic and electric componenst. In this paper, a torque converter is analized by bondgraphs following a set of four first-order differential equations describing torque converter charavteristics. A new bondgraph model of torque converter is presented for establishing a bondgraph of a stator. In this new bondgraph, the converter range and the coupling range are represented clearly. In the converter range, stator is not rotating, but tranmits the torque to the tranmission case, so the bondgraph must have a gyrator element for the stator. On the other hand, in the coupling range, the stator are free to rotate, so the bond of stator is omitted. By use of this new bondgraph, the transient condition from converter range to coupling range becomes possible to estimate. Dynamic characteristics of this torque converter can obtained easily by a bondgraph simulation in comparison with the usual simulation method.
