Abstract
The calculation method of Kingpin Inclination Angle of Automobile Wheel Suspension Parameters can not be expressed explicitly, and it can only be infinite approximation to the real solution by repeated trial calculation based on mathematical model. This also determines that the Kingpin Suspension Parameters of the vehicle can not be measured directly, and can only be calculated by simplifying the mathematical model. Using gradient analysis to select data points combined with the experimental test method to analyze the correlation between the measurement value of the four-wheel aligne instrument and the set value of the four-wheel aligner, the system analyzes the changing trend of the measurement point. Select effective measuring points according to the analysis results, with a small amount of measurement data can represent the deviation characteristics in the whole range, providing a scientific basis for the selection of wheel suspension parameter detection points, while greatly reducing the testing workload so that the formulated standard has a strong executable, and provides a reliable basis for the vehicle factory inspection and performance testing data measurement points scientific and reasonable selection.
