Abstract Piezoelectricity is strongly dependent on the preferred domain orientation. A fiber-like texture of a Navy VI Lead Zirconate Titanate (PZT) piezoelectric ceramic can be induced by electric poling. This texture can be further changed and strengthened by cross-poling, that is, applying a strong electrical field perpendicular to the original poling direction. In this paper we show preferred domain orientation changes and anisotropy transitions associated with poling and cross-poling in PZT piezoelectric ceramic. The poling and cross-poling induced textures can be explained by three-dimensional orientation dependent domain switching. Based on this discussion, we demonstrate that it is possible to tailor the preferred domain orientation distribution and improve anisotropic properties of piezoelectric ceramics by directional control of the 90° domain switching using cross-poling.

Coupled vibration between transmission shaft and drive axle gears is one of the main factors influencing NVH in the FR transmission system. Based on the transmission shaft and drive axle gears, using UG to establish three-dimensional model, establishing flexible-body dynamics model and solving coupling vibration laws of transmission shaft and drive axle gears by ADAMS, and analyzing influencing factors on coupled vibration between transmission shaft and drive axle gears.It is of theoretic significance, for design parameters and installation matching between transmission shaft and drive axle gears.
