For the problem of a magnetoelectroelastic cone under concentrated loads (include torsional moment Mz leads to torsion, concentrated force Pz and point charge Q lead to compression, concentrated force Px and concentrated moment MN lead to bending) at its apex, the potential functions were constructed by a linear composition of a group o.

Because of the geometry coupling of the conical magnetic bearing,more parameters need to be considered in its design.

The geometry coupling effect and current coupling effect of conical magnetic bearings are analyzed.

Thermal magnetoelectroelasticity is a kind of special composite materials that can achieve transformation among mechanical energy, electric energy, magnetic energy, and heat energy.

An new design of changing cyclinder spiral spring into equal pitch circular cone spring is presented for spring system and the calculation formula of circular cone spring s bending and transverse stiffness is derived.

For the orthotropic magneto-electro-elastic plane problem,a series of magneto-electro-elastic beams is solved and the corresponding exact or analytical solutions are obtained with the trial-and-error method on the basis of the general solution in the case of four distinct eigenvalues,in which all physical quantities are expressed by four displacement functions in terms of harmonic polynomials.
