RACE (Rapid Axle Concept Evolution) is an end-to-end MBS (multibody simulation) software package for the development of suspension systems. It combines model build, model parameterization, post-process, data storage, and report generation into a single platform. It is cloud-based, requires no software installation and can be run from a web browser on any computer, phone or tablet.
RACE requires user inputs to define the layout and tuning of the suspension system. Once the inputs are submitted by the user, the RACE pre-processor builds a full suspension multibody simulation (MBS). RACE then runs a virtual kinematics and compliance (K&C) test cycle on the suspension system. The K&C test applies vertical, roll, steering, cornering, traction and braking loads to the suspension system and the response of the system to each is recorded. The raw simulation output is exported to a post-processor which generates a set of Key Performance Indicators (KPIs) to analyse the performance of the suspension system. These KPIs form the basis of the RACE Software suspension performance report which is generated and uploaded to the user’s account for review. The video below shows the complete process of running RACE on a double wishbone suspension system.

RACE Software – Kinematics and Compliance (K&C) Tests
RACE Software Kinematics Tests
• Vertical Motion: ±50mm parallel wheel travel.
• Roll Motion: ±50mm opposite wheel travel. The test is run with the anti-roll bar connected (RACE
Advanced and RACE Pro only).
• Steering Input: ±50mm steering rack travel in RACE Standard. The steering rack travel is user defined
in RACE Advanced and RACE Pro.
RACE Software Compliance Tests
• Lateral Force: ±3000N lateral load applied at the tyre contact patch. The loads are applied in-phase
(load applied to left and right wheel in the same direction) and anti-phase (load applied to left and right
wheel in opposite directions). The tests are run with the load applied at the contact patch (0mm trail)
and with the load applied 30mm behind the contact patch (30mm trail). (Anti-phase tests are run in
RACE Pro only)
• Braking Force: ±3000N longitudinal load applied at the tyre contact patch. The test is run with the
load applied to both wheels and also with the load applied to the left wheel only. (Single wheel test is
run in RACE Pro only)
• Traction Force: ±3000N longitudinal load applied at the wheel centre. The test is run with the load
applied to both wheels and also with the load applied to the left wheel only. (Single wheel test is run in
RACE Pro only)
• Tyre Aligning Torque: ±300Nm torque applied at the tyre contact patch. The moments are applied
in-phase (moment applied to left and right wheel in the same direction) and anti-phase (moment applied
to left and right wheel in opposite directions). (Anti-phase test is run in RACE Pro only)
