Efficiency comparison of various friction models of a hydraulic cylinder in the framework of multibody system dynamics

Abstract Dynamic simulation of mechanical systems can be performed using a multibody system dynamics approach. The approach allows to account other physical nature, such as hydraulic actuators. In systems, the nonlinearity and numerical stiffness introduced by friction model cylinders an important aspect consider in modeling because it lead poor computational efficiency. This paper couples various models cylinder with equations motion hydraulically actuated monolithic framework. To this end, two static models, Bengisu–Akay Brown–McPhee model, dynamic LuGre modified are considered work. A four-bar mechanism is exemplified case study. four approaches compared based on work cycle, force, energy balance, It concluded that numerically most efficient well able describe usual characteristics systems.
