| Abstract: | In order to seek performance advantages in the dynamic stability of piezoelectric primary members and find out characteristics of influences of the damping on structure dynamic stability,taking the proposed piezoelectric primary member for the calculation model,the dynamic equation of piezoelectric primary members was established and its dynamic stability properties in periodical loads were studied.The dynamic instability areas of piezoelectric primary members in the damping effects were discussed considering and not considering the mechanical electrical coupling,which provided related basis for the intelligent control of space steel structures. |
