3.2 Unimorph (Homework 3)
Clamping/Supporting Configuration


PROBLEM - 3D Rectangular Plate, PZT4 and Brass = 40mm x 6mm x 1mm, Two-End Support


  • We will consider a two-end supporting mechanism of the unimorph without losing the displacement
1.
Adding 5 mm long brass plate (left figure on the top), calculate the center displacemnt for the both-end support (clamped) unimorph.
2.
Adding clipped 5 mm long brass plate (right figure on the top), calculate the center displacement for the both-end support (clamped) unimorph. Use a thin brass plate (such as 0.2 mm) for the clip parts.
3.
Compare the static center displacement (100 Hz) under 1 V applied, discuss the merit of the supporting mechanism.

HINT:

Both-end clamp unimorph under 1 V applied (+0.017mm)
Both-end clam unimorph under 1 V applied (+0.022mm)
