Electro-Hydraulic Component Validation and Test System

Our client was developing a windshield wiper fluid heater and required a mid-development laboratory hydraulic test stand to validate various development changes to a prototype part.

The test system stores and delivers test fluid (washer fluid) to the device under test (DUT). Pressure, flow and temperature of the fluid are regulated and monitored. Heated fluid is cooled by the test stand and returned to the storage tank.

The quiescent and operating currents and voltages of the DUT are monitored, and a programmable DC power supply simulates vehicle battery voltage.

The complete system is controlled using National Instruments hardware and custom software written in LabView. The software capability includes report generation to a local color printer.
