Computerized test replicates actual service

A computerized process for vibrational shock testing of missile fuse components automatically simulating a wide range of conditions was developed to meet greater reliability demands. The method takes a few seconds, is repeatable, provides a permanent record of test data, and can save some of the cost of dynamic tests which require actual missile launching. It utilizes a Transient Waveform Control (TWC) technique with a digital minicomputer completely controlling test parameters. System accuracy is illustrated by comparison of an acceleration time record taken aboard an in-flight missile with the same event reproduced on the TWC system with the average error of less than 10%. The TWC method has also been used to replicate other standard waveform complex field shock signatures up to 50 g peak acceleration and 20 to 25 millisecond duration and can be further extended to cover up to 500 g peak acceleration and 1000 millisecond duration.
