Design and Research on the Test and Analysis System for the Proportional Relief Valve Characteristics
With economic and practical as a starting point, we design and develop the hydraulic platform for proportional relief valve characteristics and automatic test and analysis system that based on virtual instrument and MATLAB software. A new modular design (MD) has been applied to test method for proportional relief valve characteristics, which realized the real-time data acquisition for multi-path pressure signal of automatic measurement & control and hydraulic system for steady state and dynamic state of DBE series proportional relief valve, and conducted analysis such as time domain, frequency domain, visualization and so on to collected data, obtained rather valuable test data and characteristics conclusion. Experiments show that this system has reasonable design and stable performance, enhances the test precision, improves the test method, enriches the analysis means and has good cost performance and research practicability.
