With a view of creation of drives on the basis of electroactive polymers the structurally functional analysis of a natural prototype - a muscular fabric is made and the phenomenological model allowing adequately to describe processes of isotonic reduction and generation of effort of a muscle in isometric conditions is offered. At model identification experimental dependences of reduction of a muscle on time are used at isotonic excitation for three various loadings.
