Structural Design and Simulation Optimization of New Type Telescoping Heavy Hydraulic Trailer Steering System
The length variability of telescoping heavy hydraulic trailer wills casue friction and sliding, increasing drag torque and power consumption of steering, moreover, and reducing the security and reliability of steering, so the new type follow-up steering system is designed and studied. In order to reduce the turning radius and tire wear, the adjustable steering wheel structure and double front axle mechanism are designed. On this basis, the theoretical analysis of the steering system is carried out, and the mathematical model is established. The minimum error of actual and ideal angle is regarded as the optimization goal of pure rolling condition, and the simulation optimization and experimental research is done. The results show that: the steering structural optimization is feasible, the performance is optimal on the condition that the actual and ideal angle valves of inside and outside wheels of each axis are approximately equal in turning process, and can reflect the advantage of new follow-up steering system in lowering power consumption, improving product life cycle and other areas.
