Abstract
We study the approximation of finite-dimensional rate-independent quasistatic systems, via a vanishing-inertia asymptotic analysis of dynamic evolutions. We prove the uniform convergence of dynamic solutions to a rate-independent one, employing the variational concept of energetic solution. Motivated by applications in soft locomotion, we allow time-dependence of the dissipation potential, and translation invariance of the potential energy.

Sometimes Froude’s number for crawlers is defined as
$$\begin{aligned} \text {Froude's number}:=\frac{\text {inertial forces}}{\text {gravitational forces}}=\frac{v_\mathrm {char}^2}{gL_\mathrm {char}}\quad \left( =\mu _\mathrm {char}\, \frac{m_\mathrm {char}\, L_\mathrm {char}}{T_\mathrm {char}^2\, F_\mathrm {char}} \right) , \end{aligned}$$which is the same expression used in legged locomotion. The validity of this second definition is based on the assumption that the normal load proportional to dry friction forces is caused by gravity, so that \(F_\mathrm {char}= m_\mathrm {char}g\mu _\mathrm {char}\). The two notions are thus related by setting the characteristic speed as \(v_\mathrm {char}=L_\mathrm {char}/T_\mathrm {char}\). We prefer definition (1.4) for two reasons. Firstly, it provides a direct measure of the relevance of inertia in the gait, without the need to compare it with the characteristic friction coefficient \(\mu _\mathrm {char}\). Secondly, not necessarily the normal load is produced by gravity: consider for instance a crawler underground or in a pipe.
