Tire Physical Models developed by MegaRide make up the RIDEsuite. It comprises four modular packages, able to simulate in detail the thermodynamic, dynamic, multicontact and tribological phenomena concerning tire interaction with the road and the track
Naples, 3 October 2022. MegaRide launches RIDEsuite v22 for the automotive market: the complete simulation platform that cuts time and costs in the development and testing phases of both tires and vehicles – for applications on the road and in motorsport. RIDEsuite is a modular and multiphysical platform consisting of four applications, which are able to simulate in detail and with high reliability the physical phenomena that affect a vehicle when interacting with the external environment. This is done by constantly monitoring tire temperature, wear, footprint, grip and road surface conditions, considering these factors both in isolation and all together.
Major improvements:
weaRIDE
the tire wear model, with a redesigned contact model to more efficiently model the interaction between the road roughness and the viscoelastic properties of the compound
thermoRIDE
the thermal model, enriched with improved formulations concerning strain energy loss and convection heat exchanges
Novel parametrization modes
now present within the the tools to improve the overall user experience and to enable an easier management of new data formats
Improved numerical precision and stability
RIDEsuite v22 full updates
- Improved physical sensitivity to road roughness impact on temperature and wear (see figures below)
- Improved numerical stability, addressing tire low-speed dynamics
- State-dependent updated formulation for modelling of external convective heat exchange and tire internal strain energy loss
- Improved thermal dynamics concerning carcass / inner liner transients and warmup
Improvements in temperature and pressure evaluation in warmup phases due to thermoRIDE v5.0 physical updates
- Redesigned contact model, now able to take into account of the material properties of the tire/road surfaces in mutual contact, of the tire compound viscoelastic properties and of the road roughness for a wide frequency range
- weaRIDE v22 response is influenced by the entire temperature gradient of the tire tread
- The .config file has been updated to take into account of the road roughness properties and of the tread compound loss factor. Geometrical spec properties are now available in the standalone .wea files
- Improved formulation concerning the evaluation of the contact patch centre, taking into account the effective radius variable
- Improved camber angle local sensitivity and impact on the contact patch shape and extension
- Preinstalled multicontact core functionality in VI-CRT (road engine) and rFpro (terrain server) road simulation environments
RIDEtool v2.0
- Added new parameterization mode, allowing to interact directly with the image data
- Updated to the Matlab runtime 2021b from 2018b libraries (faster UI loading, better responsiveness and more “stable” experience)
- Improved SaveRestore process, extended for Tangential dynamics section
- Optimized overall performance and extended reliability within the user experience
RIDEtire v1.0
- Designed as a standalone macro-API for the RIDEsuite product family, pre-implementing the RIDEsuite models’ workflow, for an easier integration with the wheel carrier and the interaction with the external road engines
- Unified parameterization and configuration files to facilitate the work in external environments
