Evaluation of Hydraulically InterconnectedSuspension Systems on TARA Machine

Abstract: The TARA machine from Volvo is equipped with hydraulic suspension which can be connected with each other in different ways. The present study focuses on enhancing the dynamic performance of the TARA machine during its operations through the investigation of various hydraulically interconnected suspension (HIS) systems. Employing a comprehensive cosimulation approach using Adams Car (ACar) and MATLAB Simulink, a full-vehicle analysis was conducted. The TARA machine was modeled in ACar, while the Simulink environment was utilized to design the control system and implement the HIS configuration. The HIS system was connected within two wheels, explored with three different connection types: pendulum, cross or individual connections. The model was simulated in pitch, roll, bounce and warp modes, achieved by running on different road conditions generated in ACar. The change of different HIS systems were achieved by manipulation of the hydraulic circuit in Simulink. By analyzing the dynamic performance of the HIS systems in terms of acceleration, the study aims to identify the most favorable HIS configuration on TARA machine. This investigation provides valuable insights for optimizing the overall operational dynamics of TARA machines, thereby contributing to the development of advanced HIS systems in the field.
