Translational Spring Damper

Linear 1D translational spring and damper in parallel

 Description The Translational Spring Damper (or Spring Damper) component consists of spring and damper elements connected in parallel.
 Equations $f={f}_{c}+{f}_{d}=-{f}_{a}={f}_{b}$ ${f}_{c}=c\left({s}_{\mathrm{rel}}-{s}_{\mathrm{rel0}}\right)$ ${f}_{d}=d{v}_{\mathrm{rel}}$ ${s}_{\mathrm{rel}}={s}_{b}-{s}_{a}$ ${v}_{\mathrm{rel}}={\stackrel{.}{s}}_{\mathrm{rel}}$ $\mathrm{lossPower}={f}_{d}{v}_{\mathrm{rel}}$
