Acceleration Loads
Acceleration loads can be found, for example, in the structural mechanics analysis of an airplane seat. Acceleration or deceleration of the aircraft produces a force that an accurate simulation must include. Because expressions can be used when specifying loads, it is easy to model acceleration loads.
For modeling rotating parts under static conditions, use centrifugal acceleration loads. The body load in the radial direction is
(2-16)
where
ρ
is the density of the material,
ω
is the angular frequency, and
r
is the radial distance from the axis of rotation. A cylindrical coordinate system is often useful here.
