Analysis of a High-frequency Vibration Transmission of an Agricultural Tractor Using Dynamical Energy Analysis

Abstract

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.
