Release notes v5.0

Update version 5.0

 

  • 1D IR-TRACCs are deleted from WorldSID v5.0. 1D IR-TRACC is the old standard hardware. Rib deflection is measured by 2D IR-TRACCs right now for WorldSID 50th, both of hardware and software.

 

  • *CONSTRAINED_JOINT_STIFFNESS… of 2D IR-TRACCs are modified to deal with the blocked and NAN problem in IR-TRACCs.

 

  • MECHANISM for IR-TRACCs are created. This is for IR-TRACCs initial position and work for pre-processor (Primer, ALTAIR Hypermesh, BETA CAE-Systems ANSA…).

 

  • Thickness of thorax-rib’s damping material is variable by parameter.

 

The control-parameter is &trd_opt and located at the first place of block *PARAMETER. There are 4 difference optional thickness for thorax-rib which can be chosen by changing the parameter &trd_opt.

&trd_opt == 1: The thickness of thorax rib (Damp-MAT) is 3.00mm.
&trd_opt == 2: The thickness of thorax rib (Damp-MAT) is 3.45mm.
&trd_opt == 3: The thickness of thorax rib (Damp-MAT) is 3.90mm.
&trd_opt == 4: The thickness of thorax rib (Damp-MAT) is 4.35mm.

Original thickness of thorax-rib’s damping material is 3.00mm after calibration.

  • WorldSID v5.0 is defined with control parameter of thickness of thorax-rib’s damping material. The nodes ID and elements ID in WorldSID v5.0 can’t be renumbered. For number crash problem and number range distribution: WorldSID v5.0 must be included by key-word *INCLUDE_TRANSFORM

 

  • WorldSID v5.0 provide the function of pre-position for 2D IR-TRACCs (rib pre-position). Before the simulation of rib pre-position, the thickness of thorax-rib’s damping material must be chosen. After the simulation of rib pre-position, the control-parameter &trd_opt can’t be changed anymore, one simulation of rib pre-position according to just only one thickness of thorax-rib’s damping material.

 

Geometric modifications

 

  • Symmetry jacket, This finer jacket is optimal for EuroNCAP Far-Side simulation.

  • Arm-sleeve is a include key-file in WorldSID v5.0. This can be switched very easy in dummy-key-file. Without arm-sleeve model is stander model for EuroNCAP Far-side test.

  This include file is: worldSID50_pdb_vx.x_arm_sleeve_vx.x.key

 

                                                             with arm-sleeve                                         without arm-sleeve

  • Arm validation is improved. WSID v4.0 still has a relative soft half arm. The bending behavior of arm is improved in WSID v5.0. In the following a half-arm component test is shown for both versions of WorldSID:

  • Length and relative rotation of IR-TRACCs

 

There is evaluation method for the length and relative rotation of 2D IR-TRACCs from WorldSID 50th v5.0 which are measured by key word CONSTRAINED_JOINTSTIFFNESS_TRANSLATIONAL_TITLE and CONSTRAINED_JOINTSTIFFNESS_GENERALIZED_TITLE.

For evaluating signals of length use the output of the jntforc File. Then use type 0 and evaluate y- displacement.

For evaluating signals of relative rotation use the output of the jntforc File. Then use type 1 and evaluate z- displacement.

Some post processors show different component output name. In this case evaluate as follows:

For CONSTRAINED_JOINTSTIFFNESS_TRANSLATIONAL:
theta_degree = y-displacement, length of 2D IR-TRACCs

For CONSTRAINED_JOINTSTIFFNESS_GENERALIZED:
psi_degree = z-displacement, relative rotation degree of 2D IR-TRACCs

The CONSTRAINED_JOINT_STIFFNESS_TRANSLATIONAL cards IDs are as follows:

ID Title Local direction component
1043 IR Tracc Shoulder rib length y-coordinate theta_degree
1044 IR Tracc 1st Thorax rib length y-coordinate theta_degree
1045 IR Tracc 2nd Thorax rib lenght y-coordinate theta_degree
1046 IR Tracc 3rd Thorax rib length y-coordinate theta_degree
1047 IR Tracc 1st Abdomen rib length y-coordinate theta_degree
1048 IR Tracc 2nd Abdomen rib length y-coordinate theta_degree

 

The CONSTRAINED_JOINT_STIFFNESS_GENERALIZED cards IDs are as follows:

ID Title Local rotation's direction component
1051 IR Tracc Shoulder rib rotation z-coordinate psi_degree
1052 IR Tracc 1st Thorax rib rotation z-coordinate psi_degree
1053 IR Tracc 2nd Thorax rib rotation z-coordinate psi_degree
1054 IR Tracc 3rd Thorax rib rotation z-coordinate psi_degree
1055 IR Tracc 1st Abdomen rib rotation z-coordinate psi_degree
