Dual Front Axle Heavy Vehicle Steering System Modeling And Optimization

With the rapid development of the national economy for many years, truckmarket, rapid development, and heavy-duty truck laden car is the main direction ofdevelopment. Dual front axle steering system used widely in the commercial field,dual front axle steering with heavy truck transport because of high efficiency, lowcost transport, road transport has become the first choice, but in actual use dual frontaxle steering The prevalence of heavy truck tire abnormal wear, easy to deviation, thedirection of the heavy swing of serious problems. The research in the existingconditions, the use of dual front axle steering system, steering characteristics,high-end requirements of a heavy truck company in the second generation of a modelof the double front axle steering system is optimized to achieve the reduction of thesteering Tires for abnormal wear, steering light of the higher requirements.Taking a company to study heavy-duty vehicles, first introduced the vehiclesteering system of the type, composition. Analyzes the leading dual front axle steeringsystem steering wheel abnormal wear of factors. Once again for the movement ofcargo between steering system uses planar projection method, the problem space intoa plane to analysis, calculated model; Secondly, a steering system and suspensionsystem model motor coordination, and steering the movement of leaf springsuspension and analysis of interference, the interference amount of abnormal wearand tire size are closely related; Finally, hydraulic power steering system in apreliminary calculation of the hydraulic components. It also describes the ADAMSsimulation software features and functions, review the use of ADAMS/View moduleanalyzes the theoretical basis of dynamic simulation and analysis. And theestablishment of the overall steering system model, the steering system kinematics,dynamics simulation, the steering system on the basis of a preliminary evaluation.The subject of steering system for heavy vehicle design and development to provide amore scientific methods to improve the design quality, effectively shortening thevehicle development cycles, reduced development costs, to improve the quality ofproduct design and manufacturing to explore a new way.
