Piezo Actuator Stroke & Force calculator
Free stroke and blocking force from d33, voltage and stiffness.
Category: Active Optics
Formula: ΔL = d33·V·N · Fb = k·ΔL
Inputs
| Input | Parameter | Unit | Default |
|---|---|---|---|
| d33 (pm/V) | d33 | 500 | |
| Voltage | V | V | 100 |
| # layers | N | 100 | |
| Stiffness (N/µm) | k | 50 |
Result with the default inputs
- Free stroke: 5 µm
- Blocking force: 250 N
Open it with your own values: put each input in the address as a parameter, for example /calculators/piezo-actuator-stroke-force?d33=500. A unit other than the listed one goes in <parameter>_unit.
