Abstract: Based on the sensitivity analysis, an integrated control2structure design optimization method is proposedfor piezoelectric trusses. In the studied problem, the objective function and constraint functions not only include theconventional structure design indexes, but also include vibration control indexes, and the control design variables andstructure design variables are optimized simultaneously. Numerical example demonstrates the effectiveness of themethod and the program.
