This paper presents the inverse dynamic analysis of the hydraulic excavator manipulator based on<br/> the experimental data. A three dimensional rigid multi-body model of the hydraulic excavator<br/> manipulator was built up. Inverse dynamic analysis for typical operation mode was carried out by the<br/> ADAMS program. In order to verify the analysis results with the measured, the hydraulic pressure and<br/> displacement of the cylinders were measured and the dynamic analysis was carried out using<br/> experimental data. From the results of the cylinder driving forces, good agreements are obtained<br/> between the analysis and the measurement.

Structural intensity has been mainly utilized to identify vibration energy flow in a vessel. In this paper, the structural intensity of a shuttle tanker subjected to H-moment of the main engine was calculated using a finite element model. From the analysis, it was found that the top-bracing elements, which support the main engine onto the hull structure to prevent the excessive transverse vibration of the main engine, play the role of the dominant path and sink for vibration energy flow from the main engine. Therefore, the structural intensity was controlled by the modification of stiffness and damping characteristics of the top-bracing elements. As a result, it is observed that the transverse vibration level at the center of navigation bridge deck decreased after the control of structural intensity.

This paper presents the inverse dynamic analysis of the wheel loader manipulator based on the experimental data. A three dimensional rigid multi-body model of the wheel loader manipulator was built up. The inverse dynamic analysis for the typical operation mode was carried out by the ADAMS program. In order to verify the analysis result with the measured one, the hydraulic pressure and displacements of the cylinders were measured and the inverse dynamic analysis was carried out using experimental data. From the results of the analysis and measurement, it was concluded that the computational driving force showed good agreement with the measured one.
