Mechanical Properties Evaluation for Pneumatic Actuator and Electric Actuator Based on AHPFCE

摘要

—The actuators’ mechanical properties evaluation is a fuzzy concept with multiple properties and classes. The fuzzy data quantification, analytic hierarchy process and fuzzy comprehensive evaluation (AHP-FCE) methods are combined to establish the actuators’ mechanical properties evaluation (MPE) model. The flowchart of actuators’ MPE and selection on AHP-FCE was considered and characterized in detail. The weighted average principle has been taken to replace the maximum membership principle in dealing with the actuator’ mechanical properties comprehensive value. One pneumatic actuator and one electric actuator in same working demand are taken as an example to verify the evaluation model. The result shows that it is effective, correct, easy to apply and worth to being recommended in similar evaluation field.
