The SA function returns the value of the acceleration at a given location S along a beam. The value of S ranges between 0.0 and 1.0. A given value of S determines a unique location along the axis of FE_PART.
When evaluating the loads during a simulation, Adams Solver C++ sets the value of S at every integration point and computes the value of the distributed load and its derivatives. Accordingly, it sets the value of the function SA depending on the specified component.
Format
SA(comp)
Arguments
comp | An integer value specifying the kinematic component at a given position. All values are in the global frame. 1 = x component of acceleration 2 = y component of acceleration 3 = z component of acceleration 4 = x component of angular acceleration 5 = y component of angular acceleration 6 = z component of angular acceleration |
Example
FE_LOAD/1, FE_PART=3, FX=3.3*(SA(1)-ACCX(7))
In this example, the distributed load depends on the global x acceleration along the beam.
