Study on instant original characteristic calculation and matching method for torque converter test automation

To obtain the original characteristic of torque converter automatically and efficiently, a test automation system of torque converter is set up based on electric power cycling technology, and a test automation software is programmed by Labview language based on serial communication and technology. This test automation system realizes the load electric power recovery, test data acquisition and processing, the torque converter original characteristic curve generation, matching calculation with the engine, saving the test data and curve pictures, and the formal report generation automatically. The high efficiency and convenience of the test system are illustrated by a practical application.
