The in-plane vibration transfer function of heavyloaded radial tire based on the in-plane rigid–elasticcoupled model is researched and validated by experiment, including: 1. The in-plane vibration modal test and analysis with the coupled feature of tread and sidewall is proposed and implemented; Figure 25
The in-plane rigid–elastic-coupled tire model is derived, and the backward structural parameter identification is validated with the experimental result; 3
Summary
As the heavy-loaded radial tire, GL073A ADAVANCE tire has the characteristics of load heavily and widely applied to weapons platform. Taking the structural feature of the heavy-loaded radial tire into consideration, the modified modal analysis method considering the coupled characteristic of tread, sidewall, and rim is proposed and implemented, which is shown, including tire support device, force hammer and charge amplifier, data test system, and PC computer. Vectors being orthogonal, implying the in-plane experimental modal analysis considering the coupled feature of tread, sidewall, and rim is effective to character the vibration of frequency band within 300 Hz. The coupled equation of heavy-loaded radial tire is solved by the modal expansion method, and the partial difference equations are transformed into the time domain and space domain.
