Influence of Elastic Material Components on Dynamics of Hydraulic Cylinder Actuators via a Numerical Study

Abstract:

This research presents a numerical analysis of hydraulic actuator dynamics considering the effect of elastic material components. A hydraulic position control is established with dynamically parameters basing on mechanic theories. In which, coefficients of viscous damping, stiffness of hydraulic oil and friction of polymer seals are considered. Hence, the model can be analyzed as a mass-spring-damper system. This research employs numerical simulation for obtaining system dynamic responses. The results are consistent with theories and reality. These are useful in design and calculations of hydraulic control systems.
