A New Test Control and Data Acquisition System for Experimental Testing of Automatic Transmissions 770511

A new computerized test control and data acquisition system for experimental testing of transmissions has been developed. The purpose of the test system is to provide a better transmission product by facilitating test activities, which include performance, development, and durability testing. The test system is capable of handling many different models of automatic and powershift transmissions, varying in size, horsepower, and complexity.
The system is dedicated to test cell operation and is not used for non-test-related functions. It is a mini-computer-distributed system commonly referred to as a hierarchical system. The system consists of satellite, intermediate, and host computer levels. It is used in conjunction with ten engine-powered test stands and six DC-dynamometer-powered test stands. This paper covers operating and system features of the overall test system.
