轿车子午线轮胎高速均匀性纵向谐波力的研究

Study on Tangential Harmonic Force of High-speed Uniformity of Passenger Car Radial Tire

对轿车子午线轮胎高速均匀性纵向谐波力进行研究。结果表明:轮胎纵向波动力1阶谐波(TFV1H)幅值随着轮胎速度的增大而增大,并呈几何式增长趋势;轮胎TFV1H幅值和速度的关系可用幂函数模型表示;不同轮胎的幂函数模型的2个系数不同,但其具有较好的线性关系;可以将轮胎TFV1H幅值和速度的关系确定为只有1个待定常数的幂函数模型。

The tangential harmonic force values of high-speed uniformity of passenger car radial tires were studied.The results showed that the amplitude of the first harmonic of tire tangential force(TFV1H)increased with the increase of tire speed and showed a geometric growth trend.The relationship between tire TFV1H amplitude and speed could be represented by a power function model.The two coefficients of the power function model for different tires were different,but they had a good linear relationship.The relationship between tire TFV1H amplitude and speed could be determined as a power function model with only one undetermined constant.
