Sled Tests with Spine

For validation of the Spine we use three different sled tests which are carried out only with the spine of the BioRID. The sled is the same in all cases, but the connection of the spine to the sled is different in all three cases.

Spine fixed upto T1                  Spine fixed upto T8
                                        (a) Fixed up to T1                                                       (b) Fixed up to T8
Spine fixed upto L6
           (c) Fixed up to L6
Figure 15 : Spine component tests

 

 

Figure 15 shows the three connection cases. All cases are loaded with a 6g triangular pulse.

  • In the first case, the spine is connected from the pelvis plate up to the T1 vertebra on the sled.

  • In the second case, the spine is connected from the pelvis plate up to the T8 vertebra on the sled.

  • In the third case, the spine is only connected with the pelvis plate (L6 vertebra) to the sled.

 

For each of these cases we again had two modifications of the spine. They are:

  • the complete spine with rotational damper and with muscle substitute springs

  • spine without rotational damper and with muscle substitute springs

 

All the following results use the same colouring scheme. The black and grey curves are the test data, the green curves show the results of BioRID2 v2.0 and the red curves show the results of the BioRID2 v2.5.
