Using CAE Simulation to Develop Increased Understanding, Repeatability and Reproducibility for Testing Electro-Hydraulic Automatic Transmission Control Devices

In the field of Electro-Hydraulic Automatic Control Valves, precise output pressure control is vital for proper shift performance of the automatic transmission. With smaller operating tolerances becoming more prevalent in the industry, test stand capability becomes vital to determining product improvements, yields, and performance. With the use of Computer Aided Engineering(CAE) simulation software, a test system can be simulated mathematically and capability can be studied and quantified.
