The paper discusses a methodology for designing compliant mechanisms with piezoelectric actuation to obtain maximized deflection and force at output. The focus is on design of compliant mechanisms with multiple optimally placed and sized piezoelectric actuators. Thus the number, length and position of actuators in the body of the compliant mechanism are optimized in addition to maximizing the output deflection and force. Results demonstrate that compliant mechanisms with multiple, optimally placed actuators outperform those with a single actuator placed at a predetermined location.

Flow Propagation

The power flow active control and vibration energy propagation of crossing-shaped plate with simply support boundary conditions using piezoelectric patch as actuators are studied. The combination of modal method and traveling wave method is employed to obtain the accurate analytical solution. The feedforward filtered-X least mean square (LMS) algorithm is used to obtain the optimal control moment for minimizing the power flow propagation in the plate structures. The results have shown that the vibration energy and power flow can be well controlled by the piezoelectric actuators. The different locations of piezoelectric actuators can introduce obvious fluctuation on the control results in the lower frequency range, and the fluctuation becomes more obvious in the higher frequency range.
