Spring

Linear 1D rotational spring

 Description The Spring component models a linear 1D rotational spring.
 Equations ${\mathrm{\phi }}_{\mathrm{rel}}={\mathrm{\phi }}_{b}-{\mathrm{\phi }}_{a}$ $\mathrm{\tau }=c\left({\mathrm{\phi }}_{\mathrm{rel}}-{\mathrm{\phi }}_{\mathrm{rel0}}\right)=-{\mathrm{\tau }}_{a}={\mathrm{\tau }}_{b}$

Variables

 Name Units Description Modelica ID ${\mathrm{\phi }}_{\mathrm{rel}}$ $\mathrm{rad}$ Relative rotation angle phi_rel ${\mathrm{\phi }}_{x}$ $\mathrm{rad}$ Absolute angle of ${\mathrm{flange}}_{x},x\in \left\{a,b\right\}$ flange_x.phi $\mathrm{\tau }$ $Nm$ Torque between flanges tau ${\mathrm{\tau }}_{x}$ $Nm$ Torque applied to ${\mathrm{flange}}_{x},x\in \left\{a,b\right\}$ flange_x.tau
