The Design of Actuating Cylinder Salt Spray Testing Device Based on Lab Windows/CVI and PLC Control

Article Preview

Abstract:

The performance tests and the requirements of experiments on aircraft alighting gear actuating cylinder in the salt spray and hot and humid environment are presented in this paper, and the hydraulic system of experimental device is designed. The host computer software is developed by Lab Windows/CVI for actuating cylinder on test parameters settings, monitoring, and storage and record, The Siemens PLC are used at the sub-processors to control the salt spray experimental device. The field-test shows that the device control precision is higher to pressure, flow rate, and the parameters such as temperature, and it can realize the simulation for different salt spray and hot and humid environments. The test on aircraft landing gear by using actuating cylinder has a good human-computer interaction and communication function. The device is safe, reliable and it can reach the test requirements.
