概要

論文の詳細を見る
Detailed digital simulations and eigenvalue analyses of self-excited vibration during slippage of parallel Cardan drives were made. The effects of the stiffness and damping of flexible couplings and gearbox suspension rubber springs were studied, and measures to suppress the self-excited vibration were clarified. Experiments involving two cases of a leaf spring coupling were made by varying the stiffness and damping of the coupling and the gear box suspension rubber spring. The results agreed well with theoretical results. Experiments for a third case with a gear coupling were also made. (average total tractive effort/total driving axle load) was measured for two cases with and without self-excited vibration, and it was shown that the latter case could attain a larger μ_a.
