Fortunately, Mechanical Shock Absorption is a broad similarity-case-base to inform AWES pumping theory and practice. Automotive shock design copes with a tremendous range of conditions by a variety of features. Obviously, Deborah Numbers apply to the variable dynamic responses of shocks, and the shock absorber is a fine analog for a pumping AWES in maximizing how much energy can be absorbed with no damage to the mechanism.

This is a starting reference for tuning spring-mass Deborah Numbers, pending further sources. How funny that shock motion is technically called a "whoop".

More interesting shock-absorber knowledge. The shim-programming art is very cool logic for kitematter to apply. Next, elastic rigging analogues of the same piston-spring dynamics. This is new conceptual ground for metamaterial wave tuning-

Deborah Numbers for Passive Dynamic Stability

Ideal spring-mass resonance of a pumping AWES is a bit tricky due to the many possible combinations of rig, wind velocity, and load demand. A particular challenge is to vary elastic response optimally across all conditions. The dimensionless quantity Deborah Number of the elastic media is a primary figure of merit, the ratio of the elastic velocity to the oscillation frequency. Its an open study how best to rig passively tuned elastic responses for optimal Deborah Numbers.
