Abstract: Virtual proving ground simulation is important in vehicle product development, which requires tyre dynamic simulation in the time domain. This paper uses the modal parameter tyre model (MPTM) to obtain the static vertical properties that match the experimental results well and then presents a complete analytical model based on MPTM for in-plane time domain simulation that involves tyre rolling movement, tyre mechanics and typical working conditions. The computational method is also proposed. Results show that the steady state result is consistent with the convergent result of dynamic simulation. Further, this article presents simulation results in both time and frequency domains and compares them with experimental results, calculating rolling resistance, etc. The model and its computational method can be applied for more complex theoretical analysis and simulation in tyre mechanics.

Keywords: modal parameter; tyre modelling; time domain simulation; rolling speed; damping ratio; rolling resistance; vehicle product development; dynamic simulation; vehicle tyres; tyre mechanics.
