矿用全地形运输车转向系统设计与动态特性研究OA

To address the problem of inconsistent steering in narrow alleys for mining all-terrain transport vehicles,in order to enhance their handling stability and operational reliability,the structural design of the steering system and the analysis of influencing factors are carried out.The three-dimensional modeling of the steering structure is completed using SolidWorks,and finite element simulation is conducted using ANSYS to verify the structural strength and dynamic stability.The dynamic and hydraulic system simulation models are built based on Simulink and AMESim respectively,revealing the mechanical laws that uneven loading,impacts,and step loads cause continuous imbalance in the steering speeds of the left and right wheels by changing the force state of the wheels;it is also clarified that the pressure and flow of the hydraulic system have a coupled response,and the output torque of the motor is proportional to the pressure difference at the inlet and outlet of the hydraulic system.The research results provide theoretical and technical support for the optimization design of the steering system of mining all-terrain transport vehicles,and have significant engineering value for improving the efficiency of underground auxiliary transportation.
