Analysis of a High-frequency Vibration Transmission of an Agricultural Tractor Using Dynamical Energy Analysis
動的エネルギー解析法を用いた農業用トラクターの 高周波数領域の振動伝播解析
Dynamical Energy Analysis (DEA) has recently been introduced as a mesh-based high frequency method modeling structure borne sound for complex built-up structures. DEA is able to visualize vibration energy flow by computing vibration energy transmission with meshes. In this paper, the analysis result of DEA is compared with the measurement result in order to verify the DEA calculation result. Additionally, a result of suppressing vibration on the tractor cabin based on vibration energy flow is shown.動的エネルギー解析は近年開発された高周波数領域の振動解析手法である．構造体を伝播する振動エネルギーをFEメッシュを用いて解析することで，エネルギーフローの可視化を可能とする．本手法をトラクタに適用し有効性を検証し，エネルギーフローに基づく振動エネルギー伝播の抑制検討した結果を報告する．
