Coupled model of hydraulic circuit system and multibody dynamics system of vehicle

Abstract

The article describes development of complex model of vehicle with controllable hydraulic suspension bracket. This model includes a hydraulic circuit system model developed using the MAT LAB software, a truck multibody dynamics system model developed with the FRUND software and a control unit and control panel modules intended for user interaction with simulation process by sending commands to execute of control algorithms of a suspension bracket. Such a complex model allows simulating a control system and controllable object. The result of the work is the software tool, which allows controlling the suspension bracket almost in a real-time mode. The technology developed is used for testing control algorithms and programs as elements of a suspension bracket control unit, and over the long term other controllable systems of the vehicle.
