This paper presents an analytic study on the existence and properties of solitary waves on 1D chains of lumped masses and nonlinear springs, which exhibit a mechanical response similar to that of tensegrity prisms. The study shows that the shape of the waves depends on the wave speed, and a progressive localization of the traveling pulses in narrow regions of space is observed as the wave speed increases up to a limit value. Comparative analysis confirms that the presented study captures the wave dynamics observed in previous numerical studies on tensegrity mass-spring chains.
This paper develops an analytic study on the existence and properties of solitary waves on 1D chains of lumped masses and nonlinear springs, which exhibit a mechanical response similar to that of tensegrity prisms with locking-type response under axial loading. Making use of the Weierstrass' theory of 1D Lagrangian conservative systems, we show that such waves exist and that their shapes depend on the wave speed. A progressive localization of the traveling pulses in narrow regions of space is observed as the wave speed increases up to a limit value. A comparative analysis illustrates that the presented study is able to capture the wave dynamics observed in previous numerical studies on tensegrity mass-spring chains.
