  This paper studies the features of a homopolymer translocating through a
flexible pore. The channel is modeled as a monolayer tube composed by monomers
with two elastic parameters: spring-like two body interaction and bending three
body recall interaction. In order to guarantee the stability of the system, the
membrane is compounded by a lipid bilayer structure having hydrophobic body
(internal), while the pore is hydrophilic in both edges. The polymer is
end-pulled from the cis-side to the trans-side by a cantilever, to which is
connected through a spring able to measure the force acting on the polymer
during the translocation. All the structure reacts to the impacts of the
monomers of the polymer with vibrations generated by the movement of its
constituent bodies. In these conditions, the work done by the cantilever shows
a nonmonotonic behavior with the elastic constant, revealing a resonant-like
behavior in a parameter region. Moreover, the force spectroscopy registered as
a function of time, is able to record the main kinetics of the polymer
progression inside the pore.
