- We are in the process of updating a discussion of What is Validation and so wanted this section with the reporting on validation results for pc-crash to be separate.
- First for the Validation Optimizations Paper 2001-01-0507
- the input are listed and were set to ACHIEVE CORRELATION WITH KNOWN TEST RESULTS
- Therefore they are Optimized as part of the Optimization "Validation".
- What if you DO NOT KNOW the results you want/need?
- how to you objectively set these input variables to approximate the 50-150 millisecond collision by an instantaneous point and angle?
- the input are listed and were set to ACHIEVE CORRELATION WITH KNOWN TEST RESULTS
- The second lists to right are from paper 2012-01-0604
- Table 1 and the Table 2 list of variables which show they DO NOT include any test or variation on the sensitivity of the arbitrary and subjective "Impact Point",
- They also do not list the vehicle fixed location on each vehicle for the 'point of momentum exchange'...it is a Space fixed listing
- SO how do you determine how it compares to the area of the damage when listed as a space fixed point?
Obviously if they provided the input and/or graphics of the impact (larger than the small pics in the report (see below)
- Coefficient of Restitution"(it is listed but minor/no effect? (see figure below)) and "Contact Point Angle and MU (MU listed but minor/no effect? see figure below))".
- and other programs which include the 'instantaneous exchange of momentum) like Virtual Crash, Planar Impact Models
- Table 1 and the Table 2 list of variables which show they DO NOT include any test or variation on the sensitivity of the arbitrary and subjective "Impact Point",
And note for 2012 reference little or no variation indicated The following is from the 2012 refrence Click here to return to the previous thread (from which this was separated)
