Shock Absorber Preload Analysis using CATIA Generative Structural Analysis (FEA)

1 0 Expert
This BND TechSource video shows how to use CATIA Generative Structural Analysis (FEA) to prove the following: 1) The spring rate will be linear when the spring has a consistent (evenly spaced) pitch and a constant diameter. 2) Preloading the spring on the coil over assembly will NOT change the rate of the spring. 3) Preloading the spring on the coil over assembly WILL affect the deflection at load (length at load) of the shock absorber.
