Additional codes for aPLI overload cable indicator channels
Posted: Sat Nov 18, 2023 4:56 pm
This request was started by E-Mail and the current state of the topic is summarized here for
the discussion of the additional codes to be added.
On the aPLI there are three overload cables in the Femur and Tibia parts of the leg impactor.
(taken from cellbond manual)
For these cables there exists instrumentation to detect the activation of the cables.
So, the base coding for these measurements should be:
The important part of the discussion is about the fine location coding of the three cables.
The leg will be used to test the vehicle front and will simulate the right-side impact of the right leg.
Therefore, the y-direction of the leg is the impact direction.
(taken from cellbond manual)
The naming of the fine location could now be realized with two concepts:
A) referencing the coordinate system of the leg impactor (dummy)
B) referencing the impact direction
The B variant might be easier to adopt and more intuitive for the users of the leg,
while variant A is more consistent with the dummy coordinate system and the simulated accident condition.
The following coding proposals are available for the discussion:
related to variant A (dummy coordinate system, x direction is front)
or a variant proposed with using In/Out regarding the dummy coordinate system
related to variant B (impact direction, y direction)
A final discussion and decision are needed, before we
can add this to the database and figure.
Kind regards,
Dirk
