Abstract
Previous study indicts that load coupling has significant influence on the work flow and actuation efficiency in the systems. Theoretical coupled analysis has shown that the actuation efficiency is the highest at the stiffness ratio larger than one and this maximum value is much higher than that predicted by the uncoupled analysis. Moreover, for non-linear systems, the actuation efficiency can be twice as high as that of linear systems. The objectives of this research is to verify the theoretical coupled analysis experimentally and explore the possibility for the mechanical work to be done into the environment. The test results exactly proved out the theoretical prediction of linear and non-linear loading systems. The capability of modeling and testing of non-conservative thermodynamic cycles have also been demonstrated which make it possible to take advantage of the mechanical work out of the systems.
