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

William Harbin
in Modeling
2 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.

1 0 Expert
This BND TechSource video shows how to create a “template” part for an Involute Spur Gear. This part may be modified by simply changing the parameters of any/all of the following three formulae: z - number of teeth // real parameter [z = input] Rpa - Ref Pressure Angle // angle parameter [Rpa = input] m - module // length parameter [m = input] And the Undercutting issue can be resolved by introducing Profile Shift which affects the Center Distance between gears as well as adjusting the Addendum and Dedendum circles. Ad – Addendum circle // length parameter [Ad = input] Dd – Dedendum circle // length parameter [Dd = input] https://bndtechsource.wixsite.com/home Excel Involute Spur Gear Calculator with macro: https://drive.google.com/file/d/1b2gzKpBHfOakALJi1-hZfOqGt_KFxNLc/view?usp=sharing
