8.4 Suspension & Sway

Analyze vehicle suspension and sway dynamics

Standards catalog

Validation: indicative · Method band: advanced-numerics

Indicative method: Indicative closed-form or numerical model

Linear elastic material behavior unless noted otherwise.
User is responsible for load combinations and load factors per the selected design code.

Does not replace a licensed professional engineer or official code compliance review.

Purpose: Vehicle roll under lateral acceleration — roll angle, load transfer.

Method: Closed-form static roll model

M_{r o l l} = F_{y} \frac{W B}{2}, ϕ = \frac{M _{r o l l}}{K _{r o l l}}, Δ W = F_{y} \frac{h _{c g}}{t _{t r a c k}}

UI: Legacy layout; extracted monolith; unit profile.

Gaps: No spring–damper dynamics or ride frequency (despite catalog labels); quasi-static only.
