Vibration Reduction Method Using Transfer Function Characteristics of Operational TPA


In this study, the authors considered vibration reduction method using transfer function characteristics of operational TPA. Contribution was evaluated separately in each reference point, principal component, and transfer function of principal component. Countermeasure to the response signal was considered according to each characteristic. Floor vibration reduction of a model vehicle was performed to verify the efficiency. As a result, the vibration was reduced more with less additional weight comparing with a conventional method in which countermeasure was carried out focusing on only reference point signal. Consequently, the new method was found to be able to reduce the vibration more efficiency.本研究では,近年,短時間で振動,騒音の寄与分離が可能な手法として提案されている実稼働TPAに着目し,本手法により取得される主成分および主成分伝達関数を用いた振動低減手法について検討を行なった.模型自動車を対象に,提案手法を利用して振動低減を行なったところ,効果的な振動低減が可能となった.
