Multi-Domain and Durability Analysis of a Hybrid Hydraulic Vehicle

The intent of this paper is to present a multi-domain and structural study of a hydraulic hybrid machine. The evaluation of different solutions is based on simulation approach, using LMS Imagine.Lab (Amesim) and Ansys Workbench software packages. Amesim provides a 1D simulation suite to model and analyze multi-domain intelligent systems, to predict their multi-disciplinary performance and Ansys Workbench Durability tool performs the high cycle fatigue life calculation. The multi-domain analyses are made for different constructive solutions at different drive ratio. The comprehensive fatigue calculations and results enable engineers to evaluate the main shaft design of the hydraulic motor in order to avoid failures under real world conditions. Some recommendations are made regarding possible solutions.
