主 题:Articulated vehicle Redirector Load-sensing steering system Pressure oscillation
摘 要:Load-sensing steering systems for articulated loaders are prone to large pressure shocks and oscillations during steering operations,affecting the system *** optimized structure of the redirector with bypass damping is proposed to improve this *** this structure,orifices and throttle grooves are added to the traditional *** control the steering load and working conditions,the steering load of the loader is replaced by a pressure regulating *** and experimental results reveal that the redirector with bypass damping has better load-sensing characteristics than the traditional *** peak output pressure shock caused by the load unit step signal decreases from 6.50 to 5.64 MPa,which means the pressure oscillation of the hydraulic system is reduced by 13.4%.The pressure fluctuation time can be reduced from 2.09 to 1.6 s,with a decrease rate of 23.4%.The output pressure oscillation decays swiftly,and the smoothness of the steering operation is improved significantly.
