Solid fluid dynamic models implemented within the framework of conservation of mass and momentum in ReStackor provides an engineering analysis tool capable of quantifying the effect of each component in the shock on overall system performance and suspension operation over the entire range of suspension speeds. Tabular outputs of ReStackor pro show the fluid dynamic forces applied to the stack face as a function of damper rod velocity. I did find an older Slackmeyer stack somewhere and used it as a data point when developing my stacks. Mid-Stroke Harshness In a motorcycle fork it is desirable to have near zero spring force at the top of the stroke. All of the above examples show stack deflection as a function of force applied to the stack. Practical Results Clicker Map: Due to the stress concentration at the clamp most shock absorbers use a tapered stack to smooth the bend radius and avoid over stressing the shims.
