Synthesis of Multi-Axle Steering System of Heavy Duty Vehicle Based on Probability of Steering Angle

In the paper, the kinematics model and a mathematical optimization model for the multi-axle steering system of heavy-duty vehicle are established based on the mechanism kinematics analysis. A new weight function is designed considering the probability of steering angle. Takes 10×8 heavy-duty vehicle as an example, the parameters of multi-axle steering system are optimized. The result shows that the result with weight function has better effect than other conditions. We also develop mechanism kinematics analysis and simulation software. The work in the paper will help to guide the design of steering system of multi-axle steering heavy-duty vehicle.
