Abstract
A new compressed air engine is presented where the conversion from the thermodynamic level to mechanical motion is realized with pneumatic artificial muscles (PAMs). The engine architecture uses an original concept for the coupling of the PAM’s to the engine axle based on freewheeling clutch bearings driven by short lever arms. The operation of the motor is described with a kinematic model which is further used for a numerical simulation. Forces, torque-contributions and mechanical power and work are represented related to the angular displacement of the motor shaft. The motor energetic efficiency is also evaluated. Finally, a physical experimental set-up has been realized for the verification of the concept.
