| Abstract: | In order to prevent the pressure impact when the load-sensing hydraulic system was in the fast operating mode, hoist-ing system of truck crane was used as an example to make analysis. AMESim software was used to build the simulation model of load-sensing hydraulic system which was optimized with test data. The main reason which caused pressure impact was found. Then the exist-ing hydraulic system was optimized. The simulation results and product test data show that:the amplitude of pressure impact can be re-duced effectively using the improved hydraulic system with a three way anti-impact valve. |
