| Abstract: | In order to reduce pressure deviation of rodless cavity of hydraulic luffing cylinders on both sides while luffing down, taking a fire truck luffing system as the carrier, this paper studies and finds out causes of biased load of double cylinder, and puts forward improvement scheme. Furthermore, based on test data and electro-hydraulic system parameters, the co-simulation method is used to build electro-hydraulic luffing system simulation model and optimize the improvement scheme. The simulation and machine test results show that, using anti-biased load valve with reasonable setting pressure can effectively reduce pressure deviation amplitude while luffing down, the anti-biased load effect is remarkable. |
