Signal Noise Ratio Analysis of Fail-Safe Design in Products and Technology Development

This article analyses in detail the producing negative effects from existing interaction among controlled factors that are tested by fail-safe design in the process of products and technology development,making use of the compression stress test that is made by interference fit between the shaft and parts on the shaft,with the interaction among controlled factors producing compression stress,analysing the example, fully embodying the consequences of interation among controlled factors, and putting forward resolved methods.
