Analog.Basic.Tests.TranslationalEMF ​

Test circuit for TranslationalEMF driven by a sinusoidal voltage with a mass load.

A sine voltage source (amplitude=1 V, frequency=1 Hz) drives a TranslationalEMF (k=1 N/A). The mechanical flange is connected to a sliding mass (m=1 kg, horizontal, no gravity). The support is grounded via a Fixed component.

With an ideal voltage source and k=1:

  • vel = v/k = sin(2π·t)

  • s = (1 − cos(2π·t))/(2π)

  • a = 2π·cos(2π·t)

  • f = m·a = 2π·cos(2π·t)

  • i = −f/k = −2π·cos(2π·t)

Analogous to RotationalEMFTest in the standard library.
