Statistical Regularity of Vehicle Front Wheel Sideslip and Its Modeling

In this paper, to reveal the statistical characteristic and regularity of vehicle front wheel sideslip, with the professional side slip test-bed the front wheel sideslip values of 83 vehicles were measured. The paper further employed parameter estimation and hypothesis testing methods to confirm that the front wheel sideslip values of measured vehicles obeyed the normal distribution N (1.2306, 5.2480). The mathematical model which could describe the sideslip distribution was established. The article also examined calculations which showed that the result acquired by models was accurate and reliable; with the model calculating error 4.0759% only. Finally, this research would play a significant role in understanding the front wheel sideslip statistical characteristic and regularity of transport vehicles. In addition, it is also useful to judge vehicle traveling safety, fuel consumption and tire wear of front wheel.
