轮胎力传递率试验影响因素的研究

Study on Influencing Factors of Tire Force Transfer Rate Test

研究轮胎力传递率试验的影响因素,包括轮胎充气压力、测试敲击方式、轮辋、生产批次和加速度传感器粘贴胶。结果表明:轮胎充气压力、测试敲击方式、轮辋、生产批次和加速度传感器粘贴胶对轮胎一阶频率有一定的影响,波动范围为1~4 Hz,其中轮辋的影响最大,测试敲击方式的影响较小;对空腔频率的影响相对小一些,甚至几乎无影响;对一阶幅值比和空腔幅值比均有影响。

The factors influencing the tire force transfer rate test were studied,including tire inflation pressure,test knock mode,rim,production batch and acceleration sensor adhesive.The results showed that all the studied factors had certain influence on the first-order frequency of tire,in which the rim had the most significant influence and the test knock mode had much less influence,and the fluctuation of the first-order frequency was usually 1~4 Hz.The influence of the factors on the cavity frequency was relatively small.It was also found that both the first order amplitude ratio and the cavity amplitude ratio were affected by the factors.
