Four-bar linkages are critical fundamental elements of many mechanical systems, and their design synthesis is often mathematically complicated with iterative numerical solutions. Analytical methods based on Fourier coefficients can circumvent these difficulties but have issues time parameters assignment for path generation without prescribed in previous studies. In this paper, an improved Fourier-based point-to-point combination method presented, which generates more points by approximation...
One challenge of bearing fault diagnosis is that the vibration signals are often a nonlinear mixture unknown source signals. In addition, practical installation position also limits number observed Hence, underdetermined blind separation (UBSS) problem. this paper, novel UBSS solution based on estimation and improved sparse component analysis (SCA) proposed. Firstly, ensemble empirical mode decomposition (EEMD), correlation coefficient (CC), adaptive threshold singular value (ATSVD) joint...
