The Altair Partner Alliance (APA) has announced that multi-body dynamics (MBD) software from ChassisSim Technologies is now available for download. Traditionally used in the racing industry, ChassisSim simulates and predicts vehicle parameters.
ChassisSim allows race teams and vehicle dynamics engineers to simulate all aspects of vehicle behavior early in the design process, saving time and resources by preventing unnecessary cycles. Users can predict lap times by performing full multi-body transient simulation and then export the data for review.
Containing a number of tools and modules, ChassisSim is able to reverse-engineer several vehicle parameters based on logged data. The auto bump generation tool provides road surface properties while the aero modelling toolbox can derive the aeromap of the vehicle.
Users can also predict the tire force and properties with the tire force modelling toolbox, and utilise the shaker rig toolbox to gather frequency based results for all vehicle modes. ChassisSim can determine the fastest setup for a particular circuit based on a given vehicle model, as well as allow the driver to test a circuit using the same model to verify the simulation results.
Available for the past 13 years, Altair’s innovative unit-based licensing system allows HyperWorks users customisable access to a growing portfolio of applications, optimising their return on investment by making more than 20 in-house-developed applications available by use of a single pool of recyclable HyperWorks units (HWUs).
Altair has also offered the opportunity for third-party companies to run their own applications under this unit-based system, a collaboration now known as the Altair Partner Alliance. The overall flexibility of these HWUs empowers users via access to the largest, most complete suite of CAE applications available. The ROI increases for users each time a new application is added to the offering, since any of the partner programs can be accessed using the same leased HWUs they are already using to run HyperWorks. This makes more than 60 additional applications available at no incremental cost or long-term commitment.
‘ChassisSim is a product which has been created by race engineers, for race engineers,’ said Michael Hoffmann, Senior VP of Math & Systems at Altair. ‘It combines ease-of-use with predictive simulation technology, both of which are absolutely necessary in motorsports. The higher level of studies provided by ChassisSim allow our customers to maximise vehicle performance in a short amount of time, where they can then utilise HyperWorks to further refine the vehicle design.’
