Microcomputer Application in Generating Force Functions for Aircraft Tire Load Testing

A microcomputer is used to generate force functions for aircraft tire load testing. Using the technique of multiplexing, one can feed more than four functions signals after D/A conversion to each corresponding hydraulic system. Such a system results in better performance with respect to accuracy improvement, design flexibility, hardware requirement, and reliability than a conventional random logic circuit. A slight modification in its software program can produce several different real time functions synchronously tor asynchronously for various control applications.
