摘　　要：以215/75R17. 5载重子午线轮胎为研究对象,利用Abaqus/Explicit模拟轮胎在转鼓上的滚动过程并分析其振动特性。为了验证该有限元分析方法的准确性,采用多普勒激光测振仪测量轮胎在转鼓上滚动时胎侧测点在时域下的振动速度响应,应用Matlab中等波纹低通滤波器Firpm函数对测得的时域信号进行滤波,保留20~500 Hz频率间的振动响应信号并对其进行傅里叶变换,与频域下的仿真值进行对比,二者具有良好的一致性,证明了滚动轮胎有限元分析方法的准确性。从有限元仿真的角度分析了使用因素对胎面和胎侧振动特性的影响规律。研究表明:胎面的振动速度分布关于轮胎顶点对称,靠近接地区域振动速度幅值最大,接地后端振动速度大于接地前端;随着速度和充气压力的增大,胎面和胎侧的振动速度随之增大,载荷对胎面和胎侧振动速度的影响较小。Taking 215/75 R17. 5 truck and bus radial tire as the object,the rolling process of tire on the drum was simulated by using Abaqus/Explicit and its vibration characteristics were analyzed. In order to verify the accuracy of the finite element analysis method,Doppler laser vibrometer was used to measure the vibration response of measurement points on tire sidewall in the time domain,and then Matlab corrugated medium low pass filter Firpm function was used to filter the measured time domain signal,and the vibration frequency response signals between 20~500 Hz were retained and transformed using Fourier method. The simulated values of the frequency domain were in good agreement with the measured results,which proved the accuracy of the finite element analysis method for rolling tire. Based on the finite element simulation,the effects of velocity,inflation pressure and load on the tread and sidewall vibration characteristics were analyzed. The results showed that the tread vibration velocity distribution was symmetrical about tire vertex,the position having the maximum amplitude of vibration velocity was close to the ground,and the vibration velocity of ground back end was larger than that of ground front end. With the increase of velocity and inflation pressure,the vibration velocity of the tread and sidewall increased,and the load had little effect on the vibration velocity of the tread and sidewall.
