Abstract:
      The simulation analysis method was used to explore the rolling obstacle crossing vibration characteristics of the non-pneumatic tire.The finite element model of the non-pneumatic tire was established,the rolling obstacle crossing vibrations of the spoke type original non-pneumatic tire(referred to as the original tire) and spoke bionic optimized non-pneumatic tire(referred to as the optimized tire)were simulated and analyzed,and the effects of the rolling speeds and the obstacle heights on the radial and longitudinal vibration of the original tires and optimized tires were investigated,as well as the relationship between the vibration characteristics and the standard deviations of the grounding pressure during the two kinds of tires obstacle crossing.The results showed that the increase of the rolling speeds and obstacle heights during the two kinds of tires obstacle crossing would exacerbate the radial and longitudinal vibrations.Compared to the original tire,the vibration reduction effect of the optimized tire was mainly reflected in its stable vibration characteristics at varying rolling speeds and obstacle heights.The standard deviation of the ground pressure peak could partly characterize the vibration intensity of the non-pneumatic tire.The simulation analysis of rolling obstacle crossing vibration of non-pneumatic tire laid a theoretical foundation for the study of dynamic characteristics,and was of important significance for improving vehicle stability.
