Research on Characteristic Test System for Proportional Solenoid

The static and dynamic characteristics of proportional solenoid are closely related to proportional valves work point matching. Its dynamic performance is even more critical in high precision and frequency hydraulic control system. In order to obtain complete characteristics of proportional solenoid, a test system is built according to relative standards. The high precision feeding platform is realized with a set of ball screw and stepper motor. A multifunctional data acquisition card is used both in data acquisition and drive control. The system software is developed based on producer/consumer pattern in LabVIEW environment. And thus solenoid characteristic test process and data analysis functions are automated. Experiments show that all the characteristic tests for proportional solenoid are realized, and the results are accurate to provide experimental support for both research and design in proportional solenoid.
