八、汽车转向操纵性试验方法(一)试验目的汽车转向操纵性是汽车的主要性能之一,随着公路条件的改善,汽车行驶速度的提高,汽车转向操纵性的重要性也日益显著。它不仅直接影响驾驶人员的疲劳和行车安全,而且还影响其他性能的发挥,如动力性能、经济性能、平顺性能、越野性能等。通过测定汽车转向操纵性能的有关参数,全面地评价汽车的转向操纵性能。影响转向操纵性能的因素较多,由于条件所限,本文所述内容仅适用于中吨位载重汽车的机械式转向。另外,对有些较重要参数的测定方法(转向系刚性、效率、转向轮运动轨迹即“过度-不 Eight, the car steering maneuverability test method (A) the purpose of the test Vehicle steering maneuverability is one of the main performance of the car, with the improvement of road conditions, the car speed, car steering maneuverability is also increasingly significant. It not only directly affect the driver’s fatigue and driving safety, but also affect the performance of other performances, such as dynamic performance, economic performance, smooth performance, off-road performance and so on. By measuring the steering performance of the car related parameters, a comprehensive evaluation of the steering performance of the car. There are many factors that affect the steering performance. Due to the limited conditions, the contents described in this article only apply to the mechanical steering of medium-tonnage truck. In addition, some of the more important parameters of the measurement method (steering rigidity, efficiency, steering wheel motion trajectory that is "excessive - not
