Consequently the using of the flexible drawgear can improve the drawing status and the riding comfort conditions of the tractor-trailer combinations greatly under the condition of stationary random excitation.

因此使用柔性牵引装置后大大改善了挂接车辆在平稳随机路面激励状况下的牵引运行状况和纵向平顺性状况

Under the condition of running on the hard soil pavement with the total train mass, the riding comfort tests of the tractor-trailer combinations with the stiff and the flexible drawgear have been performed, and the dynamics longitudinal force has been studied. When the flexible drawgear was used, the theoretical results and the experimental data showed that the peak value of the dynamics longitudinal force, the peak value of the RMS of the dynamics longitudinal force, and the PSD both of the dynamics longitudinal force and of the longitudinal acceleration decreased largely.

以平稳随机路面激励状况下满载行驶作为挂接车辆的经常行驶工况，进行了挂接车辆以刚性牵引架及不同柔性牵引参数的柔性牵引装置牵引运行时的平顺性试验，柔性牵引理论分析结果与试验结果均表明，使用柔性牵引参数值接近优化值的柔性牵引装置后，动态纵向牵引力的峰值、功率谱密度峰值及均方根值均有了大幅度的降低；主车和挂车的纵向振动加速度功率谱峰值也有了很大的降低。

I don't really know, maybe it's because we are used to driving on gravel roads or snow and ice from a young age.

我真的不知道，也许是因为我们从小习惯就砂石路面或冰雪上驾驶。

The road was now paved but narrow, and every cart meant more dust, more tinkling of bells, and still more carts ahead.

现在的路面是铺过的但很狭窄，每一辆牛车都意味着更多的尘土，更多的铃声，而前面还有更多的牛车。

This intelligent toy automobile is designed based on the SPCE061A as a micro-controller, gauging its position and posture through various sensors. Among them: making use of reflecting type infrared ray sensor, photo-electricity dynatron and Hall sensor to find the black line, the barriers, find the light and check the rotate speed.
