Static and Dynamic Properties of Metal-Elastomer Helical Spring With Rectangular Wire Cross-Section

The analysis of the influence of the elastomeric element’s geometrical and material parameters on selected static and dynamic properties of metal-elastomer spring with rectangular cross-section is presented in this paper. Numerical FEM simulations presented in the paper revealed that application of even the relatively soft rubber of 50 [Sh°A] hardness as an elastomeric element may contribute to significant increase of spring stiffness. Experimental tests considering static and dynamic properties of the analyzed spring were also performed, utilizing three different types of elastomeric foam. Performed tests demonstrated high efficiency of analyzed construction in terms of vibration damping.
