Development and Signal Optimization of Bearing Pressure Test-bed for Hydraulic Multi-way Valve

The hydraulic system and working principle of multi-way valve bearing pressure test-bed were described. The virtual instrument technology based on LabVIEW was applied to the computer aided test (CAT) system of the test-bed, the real-time monitoring and control over the whole test system were realized. By using AMESim, the simulation model of the hydraulic system of pressure test-bed was built, and the nonlinear pressure slope of the super high pressure proportional relief valve was optimized. By comparing the experimental data before and after optimization, the simulation and optimization method was verified.
