【Abstract】 Hydraulic pump as a hydraulic system power source,in the construction machinery has been widely used in the performance test of hydraulic pump and evaluation methods put forward new requirements. In this paper, a performance simulation of a model pump is carried out, and a performance test is carried out using a test bed. According to the simulation analysis and experiment,a comprehensive evaluation method of axial piston pump performance is proposed.In this paper,the simulation model of the axial piston pump is established,and the numerical simulation of the pressure, flow and efficiency of the hydraulic pump is carried out by using the AMESim hydraulic simulation platform.The hydraulic test rig of axial piston pump is designed and the same type of piston pump is tested and tested. The test data are compared and analyzed, and the hydraulic pump is evaluated synthetically.Based on the analytic hierarchy process (AHP), a method of comprehensive evaluation of axial piston pump is proposed, and a comprehensive evaluation model of axial piston pump is established. By using the sum product method in statistical method, Affect the weight, through the consistency test method to determine the applicability of the weight. Combined with a hydraulic pump test results,the pump can be a comprehensive performance evaluation.Based on the C # platform, a comprehensive evaluation software system of axial piston pump was developed, which realized the automatic calculation of the weight of the comprehensive evaluation and completed the automatic evaluation of the comprehensive performance of the axial piston pump.更多还原
