Реферат: eng: Analysis of axisymmetric deformability of mechanical transducers and actuators made in the form of composite anisotropic cylindrical shells subjected to axial tension or internal pressure is presented in the paper. The shells are modelled as cantilevers with one end fully clamped and another one free hanging with a rigid solid disk attached. Based on the analytical solution obtained and formulas derived, the conversion of the axisymmetric loading (axial load or internal pressure) to the shell torsion is analysed. Effects of material elastic characteristics, angle of the reinforcement orientation, and shell dimensions on the shell deformability and the value of the reactive shear force are illustrated using the analysis of anisotropic single-layered shells. It is shown that the angle of rotation and the reactive shear force have their maximum values at certain angles of the fibre orientation. Relationships between the shells' lengths, thicknesses and the angles of the disk rotation or corresponding reactive shear forces are identified. It is shown, based on these equations, how the parameters of an anisotropic shell, delivering a required angle of the disk rotation, can be calculated.
