Abstract(J) | 車両発進時に発生するばね下振動は駆動系とサスペンション系の連成を考慮する必要がある。本研究では側面視のサスペンション、タイヤモデルに駆動系の剛性・慣性を考慮した力学モデルを構築し、実際の振動現象を再現することを確認、更にサスペンション上下共振と駆動系の共振との関係から不安定となる条件を明らかにした。 Translation |
Abstract(E) | It is necessary to consider the coupling between the power train system and suspension system for the unsprung mass vibration that occurs when the vehicle starts. In this study, we constructed a dynamic model that takes into account the stiffness and inertia of the power train system in the suspension and tire models, and confirmed that the model reproduces the actual vibration phenomenon. Furthermore, we clarified the conditions for instability based on the relationship between the suspension vertical resonance and the power train system resonance. |
