为了解决某型轿车的转向盘振动问题，本文通过对影响转向盘振动的诸多因素逐一进行分析，结合先进的试验手段和CAE分析技术，找出了引发该轿车转向盘振动的主要原因是车轮动平衡质量不合格及固定转向柱管的仪表板横梁刚度不足，通过提高车轮动平衡质量，改进仪表板横梁设计，提高仪表板横梁的刚度和固有振动频率，结合道路试验进行主观评价，改进后的转向盘振动达到了平顺性要求。

But since their repositioning on tangent track and steering on curve line are not reliable enough,they have not been applied and developed on a large scale for a long time.

本文通过理论分析和动力学计算表明，采取适当措施使独立车轮轮对以拖动的形式前进，可以有效解决独立车轮的导向问题。

And the tangent plane of three characteristic curves on the tire determines the spatial position of the tested wheel.

每个车轮使用3个线结构激光传感器，通过求取轮胎上3条特征曲线的切平面来确定车轮的空间位置。

The influence of the steering wheel alignment parameters (consisting of caster, king-pin inclination, camber and toe-in) and tyre meandering frequency on the vehicle shimmy is systematically studied. Some new conclusions having practical value are obtained and proved by the road test.

利用所建的汽车摆振数学模型，系统地研究了转向轮定位参数（包括主肖后倾角，主肖内倾角，车轮外倾角和车轮前平角）和轮胎蛇形运动频率对汽车摆振的影响规律，获得了许多新的具有实用价值的结论，并得到了道路试验结果的证实。

And when the wheel with good traction is only getting the very small amount of toque that can be applied to the wheel with less traction, your car isn't going to move very much.

而且牵引力好的那个车轮仅获得和差的车轮一样的很少量的扭矩，此时，你的车就不能正常运行。

In addition, total wheel/rail contact calculation with divided rail outline method are raised. Under the condition of considering the displacement, bouncing, yaw, roll of wheelsets and displacement, bouncing, roll of rails, minimum gap between rail and wheel were calculated by the trochoid method and divided rail outline method, we can easily judge totally real contact states of the wheel/rail such as normal one-point contact, nonnormal one-point contact, two-point contact and wheel complete lift. Wheel/rail normal forces in the two contact point are respectively calculated by nonlinear Hertz contact theory, and then, result of simulation more close to reality on actual track.

另外，提出了轨廓分区法全面计算轮轨接触状态法，在考虑轮对的横移、浮沉、摇头、侧滚和左右钢轨的横移、浮沉、侧滚的条件下，可全面地分别计算左右侧轨顶和轨侧区域与车轮的最小轮轨间隙量，以此来判断轮轨的真实接触状态：正常的一点接触、非正常的一点接触、两点接触和车轮完全悬浮，并根据非线性赫兹接触理论分别求得两接触点处的轮轨法向力，从而使仿真结果更接近于车辆在实际线路上的运行状态。

It is choice large wheel --, large public traffic, be still trundle --, sedan?

是选择大车轮———大型公共交通，还是小车轮———小轿车？

The angle that can develop continuously from the city looks, we ought to choose large wheel, is not trundle.

从城市可持续发展的角度看，我们应当选择大车轮，而不是小车轮。
