| 用加速度计测量悬置轿车轮胎的固有频率和振型，得知斜交轮胎与子午线轮胎两者的固有频率和振型是不相同的。不同气压、不同轮胎规格对其固有频率有影响，经实测证明轿车斜交轮胎也具有多于两个的固有频率及振型。用实测得到的不与地面接触的轮胎固有频率，可用于计算与地面接触的轮胎固有频率。由于斜交轮胎与子午线轮胎的振动特性及固有频率的不同，子午线轮胎在较低速度下的行驶舒适性不如斜交轮胎，故原为斜交轮胎设计的车辆换装子午线轮胎时，必须对车辆的悬架部分进行重新设计与调整。 |
| 英文摘要: |
| It was found that the natural frequencies and the vibration modes of the bias tyre were quite different from those of the radial tyre by determining the natural frequencies and the vibration modes of the suspending passenger car tyres with an accelerometer.The natural frequencies were influenced by the inflation pressure and the size of the tyre.The test result showed that the bias passenger car tyre also had more than two natural frequencies and vibration modes.The measured natural frequencies of a suspending tyre could be used to calculate the natural frequencies of the tyre which got touch with the ground.The comfortable ride of the radial tyre was worse than that of the bias tyre at the low speed.Thus，it could be concluded that the suspension of the vehicle had to be redesigned and regulated when the vehicle which used to drive on the bias tyres shifted to drive on the radial tyres. |
