After a chain composed of light particles is inserted into a one-dimensional heavy
granular chain of spheres, the formed composite chain can trap strongly nonlinear
solitary waves (SNSWs) in a light sectional chain. The light sectional chain can
reduce the peak amplitude of pulse waves imposed on the objects contacting with the
end particle of the chain. However, the effects of the light sectional chain’s
properties on the propagation velocity and amplitude of both the trapped and
output pulse waves are unclear. In this study, finite element models with
optimal parameters were established to investigate the multireflection behaviors
of the output pulse waves. Both the simulation and experimental results
demonstrated that the light sectional chain could act as a physical regulator
to tune the properties of the output pulse waves in the composite chain.
When the material of the light particle was fixed, both the propagation
velocity and amplitude of the output pulse waves exhibited the exponentially
downward trend as the number of light particles increased. Compared to the
light sectional chain of Brass, the PTFE chain could cause more serious
attenuation on the amplitude of the pulse waves and reduce the propagation
velocity of the output pulse waves. Similar phenomena had been reported in
simulation results only at the nanoscale. Even at the macroscale, the investigated
composite chain could quantitatively tune the propagation characteristics of the
trapped and output pulse waves by adjusting the material and number of light
particles.
