Computer Supported Collaborative Design(CSCD) is the applicarion of Computer Supported Collaborative Work(CSCW) in the product design field. Based on the analyse of the key technologies and problems of CSCD, a CSCD design frame faced to product design is established. Then a CSCD system faced to radar key components is founded with Pro/INTRALINK software and re-exploiting technology. Some key processes are designed too, such as database management, workflow programming, information communication, file release, conflict identification and safety management. These will provide a reference for constructing a cooperative design environment.
Based on linear magneto-electro-elasticity, the circumferential SH wave equation of transversely isotropy piezoelectricity-piezomagnetic functionally graded cylindrical curved plate is obtained. The Legendre orthogonal polynomial series expansion approach is employed to derive its asymptotic solution. The dispersion curves, electric potential and magnetic potential distributions are calculated. The influence of the piezoelectricity and piezomagnetism on the circumferential SH wave is investigated and the influential factors are analyzed. Finally, the influence of the gradient field and the ratio of the radius to thickness on the piezoelectric effect and piezomagnetic effect are illustrated.
