| Abstract(J) | 車両運動性能の開発において，タイヤの緩和長は重要な特性と考えられる．従来緩和長の測定手法は複数提案されているが，体系的な比較は少ない．本研究ではSin波入力，ステップ入力，ランプステップ入力，コーナリングスティフネスとタイヤ横バネ係数の比による推定の4手法を比較し，差異と要因を考察した． Translation |
| Abstract(E) | In the development of vehicle dynamic performance, tire relaxation length is considered an important characteristic. Conventionally, several methods for measuring relaxation length have been proposed. This study describes a comparison of four methods—sinusoidal input, step input, ramp-step input, and predicted method based on the ratio of the cornering stiffness and the lateral structural stiffness, and examines the differences and underlying factors. |
