A spring damper device , comprising: a directional spring having first and second ends , and defining an inner diameter region ; and a viscoelastic damper comprising a viscoelastic polymer comprising both an element of viscosity and an element of elasticity, and configured to extend from the first end to the second end of the directional spring to be situated within the inner diameter region of the directional spring, wherein, in response to a load on the spring damper device, the directional spring operates to compress to absorb the load and any impact shock associated with the load, and the viscoelastic damper operates to dampen vibration associated with the load, wherein the viscoelastic damper is sized and configured such that, upon a maximum compression of the directional spring, the viscoelastic damper is maintained within the inner diameter region of the directional spring so as to not interfere with the operation of the directional spring, wherein an entirety of the viscoelastic damper is situated between the first and second ends of the directional spring, and wherein during compression of the spring and the viscoelastic damper, the viscoelastic damper operates independently of the spring, such that the spring rate of the directional spring is substantially unaffected by the viscoelastic damper, the spring damper device being characterized by the viscoelastic damper comprising a first section having a first diameter (D1), a second section having a second diameter (D2), and a third section having a third diameter, wherein the first and third diameters are substantially the same and are each less than the second diameter, and wherein the first and third sections are formed on opposing sides of the second section. a directional spring having first and second ends , and defining an inner diameter region ; and a viscoelastic damper comprising a viscoelastic polymer comprising both an element of viscosity and an element of elasticity, and configured to extend from the first end to the second end of the directional spring to be situated within the inner diameter region of the directional spring, wherein, in response to a load on the spring damper device, the directional spring operates to compress to absorb the load and any impact shock associated with the load, and the viscoelastic damper operates to dampen vibration associated with the load, wherein the viscoelastic damper is sized and configured such that, upon a maximum compression of the directional spring, the viscoelastic damper is maintained within the inner diameter region of the directional spring so as to not interfere with the operation of the directional spring, wherein an entirety of the viscoelastic damper is situated between the first and second ends of the directional spring, and wherein during compression of the spring and the viscoelastic damper, the viscoelastic damper operates independently of the spring, such that the spring rate of the directional spring is substantially unaffected by the viscoelastic damper, the spring damper device being characterized by the viscoelastic damper comprising a first section having a first diameter (D1), a second section having a second diameter (D2), and a third section having a third diameter, wherein the first and third diameters are substantially the same and are each less than the second diameter, and wherein the first and third sections are formed on opposing sides of the second section. <EOS>
