On Path Oscillations Analysis of Mechanical Multi-body and Hydrostatical Driving Units Coupled System

This research deals with the path dynamics of the multi-body systems embedding hydrostatically actuating units. The main purpose of this analysis consists by an optimal dynamic response of the mechanic and hydraulic coupled ensemble, taking into account the characteristic requirements for the final path of the working tool. Theoretical background contains elements both for the multi-body dynamics of mechanical parts, and for the hydraulic driving systems. The forward analysis in terms of command action connection, and the reverse analysis in terms of system response evaluation and actuating system control frame the main research problem of this study. A computational application developed within Matlab-SimScape software was provided, and a comparative analysis between simulation data and experimental test results was presented. A practical example was developed based on the excavating equipment with a single bucket. (C) 2017 The Authors. Published by Elsevier Ltd.
