Analysis and modeling of the multidisciplinary coupling characteristics in EHA

Abstract

The Electro-Hydrostatic Actuator (EHA) system consists of many displines, however, each displine is designed separately during the design methods of the EHA. These methods always neglect the multidisciplinary coupling characteristics in EHA system and may cause low efficiency and even failure. The solution for the above problems is to analyze the multidisciplinary coupling characteristics in the EHA system. However, there is little related research at present. Therefore, this paper focuses on the analysis of the multidisciplinary coupling characteristics in EHA system and builds a complete model of the characteristics. At last, an application of this model in the EHA design indicates that the process of analysis and the model are accurate and effective.
