Modeling and Simulation for the Dynamic Analysis of a Column Assist Electric Power Steering - －Consideration of Static and Dynamic Friction Transition
コラムアシスト式電動パワーステアリングの動特性解析のためのモデリングとシミュレーション
A model is developed for analyzing the fundamental static and dynamic performance of a power steering. The basic inertia, stiffness and damping properties of each component are taken into consideration. A dynamic friction model is introduced for precise modeling of the losses of the gear meshes, the yoke support and the bearings. The torque ripple generated by the universal joints of the intermediate shaft is considered. The assist motor (brushed DC type) and its power electronics are represented in a 4-quadrant model. Static and dynamic responses of this power steering model are validated against experimental data.操舵性能における静・動特性を評価するための本モデルは，ウォームギヤ，ラック・ピニオン，インタミシャフト，ブラシ付きDCモータなどの構成要素を慣性，剛性，減衰特性で表し，モータの４象限の電気特性や，ギヤ噛合い部の動的摩擦特性を含んでいる．実験検証によりシミュレーション結果が妥当であることを示した．
