The New Construction Machinery Hydraulic Counterbalance Valve Performance Simulation And Experimental Analysis

Is of vital importance to the balancing valve is a hydraulic ba lance circuits of hydraulic components, is also in modern engineering machinery is widely used in mining, lifting machinery hydraulic components. Balancing valve, its perf ormance better also directly determine the perform ance of the whole m achine. The function of hydraulic balancing valve is used to the valve has the security protection, speed lim its, and can make the hydraulic m echanical action smoothly. To complete the working condition of bearing down, but the balance valve needs to the hydraulic system with pressure oil control, therefore, the hydraulic system pressure control, poor stability and reliability, structure is more com plex, processing is difficult. Therefore, the study of new type of engineering machinery hydraulic balance valve, its significance lies in the balance of new type hydraulic valve is superior to the traditional balance valve.Papers for the above problem s, the arti cle adopted the theo retical analysis, simulation analysis and experim ental validation of the m ethod of combining theory for the new balance valve is calculated, the dyna mic characteristics simulation analysis and experimental verification, to verify that the new balance valve good features, m ain work is as follows:(1) This paper introduces the work principle and performance characteristics of new type of balance valve, the valve is the mathematical modeling and its structure and design calculation of key parts.(2) By A MESim simulation s oftware to verify the feasibility of the v alve performance characteristics, dynam ic response analysis of hydrau lic components, the study of different parameters, hydraulic system and also for the overall assessm ent and predict its perform ance, this is the type of product design, optim ization of reference provides a quick and convenient auxiliary.(3) New balance valve AMESi m model of excavator machine system, the model simulation analysis, get the simulation results are analyzed and the m odel of 3 d visualization.By the res ult data con tains new balance valve whether the perform ance characteristics of the whole system, and provi des reference for the valve of the engine test.(4) New balance valve AMESi m model of excavator m achine system, the m odel simulation analysis, get the simulation results are analyzed and the m odel of 3 d visualization.By the res ult data con tains new balance valve whether the perform ance characteristics of the whole system, and provi des reference for the valve of the engine test.
