摘要
In this paper we present a model for a linear hydraulic actuator for multibody simulations. In addition to translational degrees of freedom also the cylinder chamber pressures are taken as state variables. In static analysis the chamber pressures are embedded thus a purely mechanical simulation can be performed. In dynamic analysis we end up to a coupled problem where the chamber pressures are separate variables. The sealing friction is taken into account in both static and dynamic analysis. For numerical solution we use a monolithic algorithm and the coupling matrices between the hydraulic and mechanic variables are presented. (c) 2014 Elsevier Ltd. All rights reserved.
