摘要
本文利用室内土槽台车模拟行驶过程中轮胎受路面激励情况,试验研究了6.00-12驱动轮胎的动刚度特性。研究结果表明:轮胎的动刚度不是常数,它随着垂直载荷、充气压力的增加而增大;滚动时的动刚度不同于静刚度。模型分析表明,在低频范围内可以用单自由度线性模型代替单自由度粘弹性轮胎模型。
The dynamic stiffness characteristics of tire 6.00-12 has been studied with the simulation of running tire vibration excited by the ro.ad, by means of the indoor soil bin tire tester. It has been shown that the tire dynamic stiffness is not a constant, which increases with the vertical load and inflation pressure, and it is different from the static one. Also, it has been demonstrated by model analysis that for the particularity of tire the viscoelastic tire model can be replaced by the linear single freedom one within the low frequency range.
