| 建立非充气轮胎高速振动的仿真分析方法，对非充气轮胎在一定负荷和转速下的高速滚动进行模拟，提取关键部件辐条和地面反作用力振动时域信号，通过结合汉明窗的快速傅里叶变换技术将振动时域信号转换成频域信号。基于建立的高速振动仿真分析方法对两种典型的非充气轮胎UPTIS和TWEEL轮胎的高速振动特性进行对比分析。结果表明，相比TWEEL轮胎，UPTIS轮胎在高速滚动过程中地面反作用力振动频域的特征振动频率少且振幅小，即相同承载能力下UPTIS轮胎的高速减振性优于TWEEL轮胎。本工作建立的高速振动仿真分析方法为非充气轮胎的结构优化提供支撑。 |

| Abstract：The high-speed vibration simulation analysis method of non-pneumatic tires was established.
The high-speed rolling behavior of non-pneumatic tires under a certain load and rotation speed was
simulated，and the vibration time domain signals of the key component spoke and ground reaction force were
extracted. The vibration time domain signal was converted into the frequency domain signal through the fast
Fourier transformation technique combined with Hamming window. Based on the established high-speed
vibration simulation analysis method，the high-speed vibration characteristics of two typical non-pneumatic
tires，UPTIS and TWEEL were compared and analyzed. The results showed that compared with the TWEEL
tires，the vibration frequency domain of the ground reaction forces of the UPTIS tire had fewer characteristic
vibration frequencies and smaller vibration amplitudes during high-speed rolling，that is，the high-speed
vibration absorption of the UPTIS tire was better than that of the TWEEL tire under the same bearing
capacity. The high-speed vibration simulation analysis method established in this work provides support for
the structural optimization of non-pneumatic tires. |
