Error analysis of measurement model and calibration method for automobile caster;

The nonlinear relationship between SAI and sensor′s measurement angle,and change of caster which affects the measurement precision are analyzed based on the model.

Calculation of the front wheel caster angle in passenger cars;

For improving the high-speed stability of a 4×4 off-road vehicle cornering on bent road,a 4-DOFs dynamics model for a vehicle is built,and the yaw rate transient responses with different caster angles at different vehicle speeds are calculated.

This text introduces the process of design improvement of the air suspension guide arm,and analyzes the guide arm and kingpin caster angle before and after the improvement.
