Abstract
Traditional simulating testing has been evolving into reliability stimulating testing. Reliability enhancement testing, an important stimulating method, can make design more robust by improving the product's reliability. In the reliability enhancement testing, omni-axis shaker is always used only because it can provide multi-axial accelerations (X, Y and Z) and six degrees of freedom simultaneously. This paper samples the vibration data on the omni-axis shaker of X, Y and Z axes from different positions under different excitations by a real-time measuring way, and conducts the stationarity, periodicity and normality checking on the basis of the acquired date. The characteristics of frequency domain, peak probability density, higher moment statistics and super-Gaussian of omni-axis shaker are analyzed. This paper shows the future development direction of reliability enhancement testing through analyzing the advantages and disadvantages of omni-axis shaker.
