Japan TOKIN Company AE0505D16, piezoelectric stack as the driving element, the material of the flexible hinge 45 steel Dimensions 25.6mm22mm,

= 3, t = 4mm. Drive and amplification mechanism connection using a combination of the preload an d adhesive. Amplification mechanism in the trial design size

When considering the piezoelectric stack amplification mechanism to maintain a certain amount of interference pneumatic accessory , and then by gluing, to avoid the the screw pretension way the insufficient.

Due to the displacement of the output are able to meet the demand of the piezoelectric pump is designed for the amplification mechanism key [5]. Therefore, the amplification mechanism displacement output characteristics

The nature of the test as the main content of this test. Entire test is completed, the system precision measurement system software prepared by the self to achieve a multi-point  china solenoid valve

Multiple cycles to measure, to ensure the accuracy of the measurement. Measured at U = 100V, the corresponding maximum output displacement amplification mechanism D = 57M, and the piezoelectric stack

Heap U = 100V, the corresponding output D = 11m, so the actual measured displacement magnification of about 5 times, while the results of the finite element analysis of up to 6 times, and said

Ming finite element analysis results close to the actual situation.
