Vertical Force Estimation of Heavy-Loaded Radial Tire Based on Circumferential Strain Analysis
In order to realize the quantitative estimation of tire vertical force, the algorithm of heavy-loaded tire vertical force estimation based on circumferential strain analysis is studied.A finite element analysis model of 16.00R20 Cat Raw tire is established.A comparison of tire loading test and modal vibration test indicates that the vertical stiffn
