Description
Block Discrete Wind Gust Model implements a model of a single gust of wind along three independent axes in a connected coordinate system.
The model is described by dependency:
Where
-
— the force of a gust of wind along the corresponding axis, m/s;
-
— the length of the gust along the corresponding axis, m;
-
— the distance traveled along the corresponding axis, m;
-
— the wind speed along the corresponding axis in the associated coordinate system, m/s.
Distance traveled calculated by integrating airspeed along the corresponding axis.
Block Discrete Wind Gust Model works in SI units.
Parameters
Gust start time (sec) — Gust start time
5.0 (by default) | scalar
The time when the gust of wind begins, with.
Gust length [dx dy dz] (m): — gust length
[120.0,120.0,80.0] ( by default) | vector 3 by 1
The lengths of the wind gust along the three axes, m. Are given as a vector. The values must be positive.
Gust amplitude [ug vg wg] (m/s) — gust force
[3.5,3.5,3.0] ( by default) | vector 3 by 1
Wind gust forces along three axes, m/s. Are set as a vector. The values must be positive.
