• Resumen

  • This paper presents a method for quickly comparing vastly different actuators based on specified performance criteria for a given application.The research grew out of the need for a technique to select actuators for space-deployable mechanisms, where stringent size constraints, expensive weight considerations and a wide selection of potential actuator types made it very difficult to compare one actuator with another without extensive analysis of each system. The method expedites the initial design selection by developing a set of expressions for various actuators that relate performance criteria such as weight and volume to the work required for the specific task. These work-based expressions, which are derived from manufacturers' data and theoretical calculations, provide a common ground for comparison and provide insight for the optimization of kinematic configurations.The process provides a quick, quantitative methodology for identifying the strongest candidate for a given kinematic configuration prior to conducting exhaustive analyses to the systems. A benchmark kinematic system typical of a space antenna deployment system is used to illustrate the generalized method.
