The Dynamics Of Multi-axis Steering Mechanism Analysis And Steering Performance Test

In this paper,the parallelogram coupled six-bar lingkage multiphase steering system was studied.including software development,simulation analysis,program design and the experimental demonstration.The mathematical model of the steering mechanism and the model of the plane force system were mainly established to analyze the steering mechanism,and then through experiment demonstrates the rationality of multi-axis steering system.Firstly,the design of multi-axis steering system was designed by using C# programming soflware.the main function is to design size,design structural and analyse stress based on Watt-? six-bar lingkage multiphase steering system.Through the visual design software,a set of ideal body size was calculated.as well as the drive moment and the axial knuckle arm of force curve were mapped.In the vehicle commonly used angle,it can better meet the Ackerman steering theory in the range of(0°,45°).Secondly,the force and torque ofthe steering system were analyzed by the actual vehicle in the steering process.In consideration of the elastic case,the dynamic analysis of the steering mechanism was indicated that the maximum rotation angle deviation was not more than 2 0 when the dimension of the steering component was changed.Then,in accordance with the principles of the actual vehicle steering control mechanism improved the design of the test bench drive components.and designed experimental electric wire dedicated cabinet.At the same time,the PLC test program was designed for the testing system.The completion of tbe test bench was built,by using the error control theory to design the plan,in tum to carry out the test analyses,including the wheel angle,the relationship of the wheel angle and steering rocker arm,the driving force and axial force under the different axial loading conditions.Ignoring the error caused by the internal friction between the test rod group,the test results and the simulation results were in good agreement with the simulation results.Through the theoretical results of preliminary design set up the test bench and carried out the experimental analysis.By analyzing the angle of the system error and the force,the reasonableness of the multi-axis steering system visual design software were verifed,and the theoretical basis and the reference were provided for the subsequent research.
