Abstract

This paper deals with the issue of analysis and examination of the factors contributing to rapidness of response time in non-linear model of electro-hydrostatic actuator. In this relation, the design and simulation of an electro-hydrostatic actuation system referred to as EHA using multidisciplinary modeling method is presented. For linear models, the bandwidth is a criteria of rapidness of response, but EHA has a non-linear model. Due to the non-linear behavior of EHA, a new method for analyzing of rapidness of response is developed and influencing factors is investigated. In this method, the ability to track a reference in special frequency shows rapidness of response of actuator. Results show the external load has a significant impact on the rapidness of response of actuator. Finally, hydraulic circuit equipment capacity influence on rapidness of response of actuator are evaluated. Changing accumulator size and pump displacement have minor effect on rapidness of response of actuator. However, results show changing cylinder capacity has a major effect on rapidness of response of actuator.
