Multi-Objective Optimisation of Tyre and Suspension Parameters during Cornering for Different Road Roughness Profiles

Effective emission control technologies and novel propulsion systems have been developed for road vehicles, decreasing exhaust particle emissions. However, work has to be done on non-exhaust traffic related sources such as tyre–road interaction tyre wear. Given that both are inevitable in efforts assessing minimising wear should considered. The amount of is because internal (tyre structure, manufacturing, etc.) external (suspension configuration, speed, surface, factors. In this work, the emphasis optimisation parameters wear, but also enhancing occupant’s comfort improving vehicle handling. addition search optimum parameters, used a tool identify highlight potential trade-offs between objectives various design parameters. Hence, initially, (based some chosen parameters) optimised with regards above-mentioned objectives, while cornering over Class A B roughness profiles. Afterwards, an optimal solution sought Pareto alternatives provided by two cases, order levels less affected under different Therefore, it required close possible they provide similar cases. Then, identified adopted suspension cases passive semi-active types. From results, significant conclusions regarding how behaves passenger handling extracted, results illustrate where converged trying compromise among above types types, semi-active, could all them more optimally.
