Improvement of Hydraulic Steering System of Explosion-Proof Vehicle Based on Numerical Analysis
The study found the phenomenon of uneven pressure regulation in the system,and in response to this problem,the study optimised the steering system using dynamics and virtual displacement theory.The first is the optimisation of the resisting moment and cylinder parameters,while obtaining the output pressure magnitude on both sides of the cylinder;then the optimisation of the hydraulic pump and constraints are used to achieve the improvement of the steering power parameters as well as the power factor and other conditions.Finally,the study selected DFH-1203G model chemical hazardous materials transport explosion-proof vehicles before and after the optimization of control experiments,the experimental results show that the optimized system pressure change tends to be stable,and ultimately stabilized at 225 MPa,compared with the initial fluctuation of the pressure trend,the optimization of the vehicle to achieve an automated pressure regulation,which can make explosion-proof vehicles to get a higher transport efficiency and safety.
