Answer
The solid height $H_s$ of a Crest-to-Crest wave spring is the height at which the spring is fully compressed and the waves are flattened. It is calculated as $H_s = Z \times t$, where $Z$ is the number of turns and $t$ is the material thickness. However, in practice, a 'theoretical solid height' may be slightly higher due to the presence of the 'gap' or overlap in the turns. Design engineers must ensure the maximum work height $H_{min}$ is at least $20\%$ greater than $H_s$ to avoid 'bottoming out,' which causes an infinite spring rate and leads to catastrophic mechanical failure of the assembly.
