This paper presents a novel signal analysis method by combining ICA and EEMD algorithms, which can be used for decomposition and feature extraction of non-stationary random signals. The features of ICA and EEMD algorithm were analyzed. Simulations verified the feasibility of combining the two algorithms. The ICA and EEMD combined algorithm has good validity and practicality in the impact acceleration...
The pneumatic frictional clutch is one of chief devices on the mechanical processing apparatus, thus its aerodynamic characteristic during normally working and the compressed air exhausting is discussed. Considering the effect of the back-moving spring in the cylinder on exhausting, and four cases of sonic or subsonic exhaust with constant volume or varying volume, the mathematical model and numerical...
