Abstract
A compressed air engine based on pneumatic artificial muscles is analysed and modelled. Pneumatic artificial muscles (PAMs) offer several advantages over conventional pneumatic cylinders: a high force-to-weight ratio, a flexible structure, minimal compressed air consumption, availability in various sizes, low cost, and high reliability. From a kinematic model of the complete mechanism, the simulation calculates instantaneous system variables such as forces, torque, and power. Energetic properties in terms of efficiency are also evaluated. The study is completed by the realisation of an experimental set-up that validates a key design innovation. The presented results explain in detail the operating principle and describe the behavior through simulation. Additionally, an original sliding anchor element, developed to resolve an inherent kinematic problem of such motors, is introduced and its function verified.
