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) |
