RACE Software Log/Updates
Version 1.3.5 Released 20/10/2024
– Added new template: MacPherson strut with split lower arm. The template is available in RACE Standard and Advanced.
– Updated 3D graphics to show attachment links when the ARB is attached to the strut in MacPherson Strut Advanced simulations.
Version 1.3.4 Released 03/05/2024
– Added ‘Percent Ackermann at full rack travel’ KPI to the steering results. 0% on this KPI means there is no Ackermann steering geometry in the suspension (i.e. when turning, the inside wheel and the outside wheel steer the same amount. This is also known as parallel steer). 100% on this KPI means that the suspension has perfect Ackermann steering geometry.
– Updated steering lock angle calculation to include static toe.
Version 1.3.3 Released 24/03/2024
– Revised K&C test descriptions in section 2 of the pdf report.
Version 1.3.2 Released 13/07/2023
– Added static toe and camber adjustment capability to Advanced templates. A second hardpoint (P20) can now be defined on the wheel rotation axis. The wheel rotation axis is along a line joining P9 and P20. P20 must be outboard of P9. For a given P20 y coordinate, static toe is controlled by the x coordinate of P20 and static camber is controlled by the z coordinate of P20.
– Improved PDF report hyperlinks from the KPI graphs back to the KPI summary table.
– Fixed a bug with the ARB attachment to strut option on the MacPherson Strut Advanced template.
– Added additional demo PDF reports and CSV files for new users.
Version 1.3.1 Released 18/06/2023
– Added ride height adjustment option to Advanced templates. This allows the user to move the suspension into bump or rebound to simulate a change in vehicle ride height before running the simulation. A positive ride height adjustment moves the suspension into bump, therefore simulating a lowered vehicle.
– Added spring installed length and spring installed load KPIs to the Static Geometry section in Advanced.
– Added additional CSV report outputs in Advanced. In addition to the existing KPI CSV report, two new reports contain the nonlinear joint curve data and the raw signals used to generate the PDF report KPI graphs. CSVs are now downloaded in a zip file containing the three csv files.
