Settings Optimization Settings
 
For the option:
Do the following:
Maximum # of Parallel Simulations
Defines the number of parallel simulation that can run parallel for generating the Advanced Transient and Cleat test data.
Check License Availability
If checked: when the number of maximum parallel simulations is larger than one, the number of available licenses will be checked when changing the number.
Show Tire Property Import Log
When clicking on the button ‘Import Tire Properties’ a log file will be shown with details about the imported properties.
Type of Solver
Defines the solver type used for the Advanced Transient and Cleat test simulations.
List Parameters During Optimization
Basic
During the ‘Basic’ optimization processes the parameters used in the optimization will be shown in the message window when checked.
Force/Moment
During the ‘Force/Moment’ optimization processes the parameters used in the optimization will be shown in the message window when checked.
Advanced
During the ‘Advanced’ optimization processes the parameters used in the optimization will be shown in the message window when checked.
Enveloping/Belt
During the ‘Enveloping/Belt’ optimization processes the parameters used in the optimization will be shown in the message window when checked.
Basic
One Degree Slip Angle Step
When checked, a one degree slip angle step will be used for the Advanced Transient (Basic) optimization and plotting, otherwise a step from zero slip towards the final slip value.
Use Fx for Rolling Resistance optimization
In case the measured rolling resistance torque (My) is not accurate, one can switch to using the longitudinal force Fx for determining the rolling resistance parameters.
Use Non-Rolling Stiffness for Tire Relaxation
In case you will not use Advanced Dynamics, and you want to use the tire non-rolling stiffness as an estimation for the tire relaxation, check this box.
Enveloping
Number of Rotations Before Cleat
The number of rotations the tire should travel before hitting the cleat in case of plotting Enveloping results.
Number of Rotations After Cleat
The number of rotations the tire should travel after hitting the cleat in case of plotting Enveloping results.
Allow Tire Stiffness Correction Enveloping
Allows to adjust the vertical tire stiffness (loaded radius parameters) during the Enveloping optimization, for example to correct for flat and ‘drum’ road test data.
Belt Dynamics
Number of Rotations Before Cleat
The number of rotations the tire should travel before hitting the cleat in case of plotting Enveloping results.
Number of Rotations After Cleat
The number of rotations the tire should travel after hitting the cleat in case of plotting Enveloping results.
Re-optimize Vertical Parameters During Longitudinal Optimization
When checked, the parameters for the Vertical Belt Dynamics will be taken into the optimization process again when fitting the Longitudinal Belt Parameters. This may give a better average result.
Weighting Factor Frequency vs. Time
Vertical
1.0 means that 100% frequency domain data of the cleat test data will be used for the optimization, when 0.0 only time signals of the cleat tests are used, when doing the Vertical Belt Dynamics parameter optimization. 0.5 means a 50-50% distribution is used.
Longitudinal
1.0 means that 100% frequency domain data of the cleat test data will be used for the optimization, when 0.0 only time signals of the cleat tests are used, when doing the Longitudinal Belt Dynamics parameter optimization. 0.5 means a 50-50% distribution is used.
Lateral
1.0 means that 100% frequency domain data of the cleat test data will be used for the optimization, when 0.0 only time signals of the cleat tests are used, when doing the Lateral Belt Dynamics parameter optimization. 0.5 means a 50-50% distribution is used.
Frequency Range
Vertical
Defines the range of frequency used for the Vertical Belt Dynamics parameter optimization and plotting.
Longitudinal
Defines the range of frequency used for the Longitudinal Belt Dynamics parameter optimization and plotting.
Lateral
Defines the range of frequency used for the Lateral Belt Dynamics parameter optimization and plotting.
Reset
Resets all values in this dialog to the default values
Ok
Will store all current defined values
Cancel
