Interview with FAW | Mechanical properties of tires under different working conditions

We spoke to Wang Wei, Engineer of Chassis Performance Control at FAW, ahead of his presentation at this November's Tomorrow's Tire Summit to get insights into what he'll be speaking about, why this research is important to the industry, challenges facing the industry, how Tomorrow's Tire can address them and more. 

Your presentation is on study on mechanical properties of tires under different working conditions, what can we expect to learn from your talk?

A: Based on the environment and conditions of tire use, as the tire performance control engineers from an automotive OEM, we studied the corresponding performance changes of the tires. The main content of this speech is the study of the mechanical properties of the tires under different environmental temperatures and different wear conditions, and the resulting tire dynamics. The model identifies the difference in results.

Why is this research important in the industry at the moment?

A: As we all know, the tire is used as the only component of a vehicle to touch the ground, and its use environment is complex and changeable. The difference in performance exhibited by tires under changing environments and conditions is very significant. In the vehicle simulation process of the OEM, the tire model used needs to consider these environmental change factors from the beginning of data acquisition, so as to improve the accuracy and rationality of the tire test data, and then obtain a high-precision tire model and Vehicle model. The study of the mechanical properties of tires under different conditions is based on the environment of the vehicle and provides an optimized direction for tire testing and tire modeling.

What are the main challenges that the industry is facing and how do you think that this conference can address them?

A: The accurate matching of tires and vehicle performance is the main challenge facing the industry. The root cause of this problem is that tire manufacturers and OEMs lack in-depth technical interactions, and they cannot focus on the issues and thus cannot exert their respective advantages. I hope that through this meeting, we can deepen the understanding of tire manufacturers and OEMs. While knowing the pain points in their respective fields, we can help both sides deepen mutual understanding and promote in-depth cooperation to form a joint problem.

What are you most looking forward to hearing about at Tomorrow’s Tire 2019?

A: To deal with the new tire technology under the trend of motorization and automation in the future; the new development of tire performance testing technology

Wang will be speaking as part of the Tomorrow's Testing session. Other speakers in the session include:

  • Liang Rongliang of CATARC who will discuss research on comprehensive test of tire field
  • Anbiao Hui of Michelin who will speak about on vehicle convey wear test & drum wear test
  • Panel discussion on tomorrow's testing and how it will impact testing facilities
