轮胎磨损与车速及排放特性的关系研究

摘要

In the vehicle other parameters are established under the precondition of tyre wear will directly af-fect the vehicle speed and vehicle speed will not only influence the vehicle performance, fuel consumption, will also affect the emission characteristics. Find out the tyre wear and the speed and the relationship be-tween the emission characteristics is very necessary. Through the established mathematical model and carries on the analysis, find out the relationship between them is analyzed. Combined with the grey theory analysis speed and emission characteristics of the correlation between. The research result shows that the speed and vehicle emission characteristics have a direct relationship between, and it is concluded that the tyre wear and emission characteristics of a direct relationship between the existence .%在车辆其它参数既定的前提下，轮胎的磨损将直接影响到车辆的行驶速度，而车辆的行驶速度不仅会影响到车辆的动力性、经济性，也会影响到排放特性。找出轮胎磨损与车速及排放特性之间的关系就显得尤为必要。通过建立起数学模型并对其进行分析研究，找出了它们之间的关系。结合灰色理论分析研究了车速与排放特性之间的关联度。分析研究结果表明，车速与车辆的排放特性之间有直接关系，进而得出了轮胎的磨损与排放特性存在直接关系的结论。
