Title
Duty Cycle Considerations for Electrohydrostatic Actuators
Scope
<p>This recommended practice provides a method of characterizing Electrohydrostatic Actuator (EHA)/Electrohydrostatic Module (EHM) duty cycles for the following purposes:</p> <p>a. To enable the comparison of the severity of different EHA/EHM applications. This allows the use of previously qualified designs without the need for repeat testing.</p> <p>b. To define parameters for endurance-test design of EHAs; e.g., a way of executing a life-equivalent test in a shorter duration by increasing the speed of cycles and/or the level of applied loads.</p>
Rationale
<p>There is a need to provide a method of characterizing Electrohydrostatic Actuator (EHA)/Electrohydrostatic Module (EHM) duty cycles in order to compare the severity of different EHA/EHM applications and to define parameters for endurance testing of EHA's. This document meets this need.</p>
