Fault Diagnosis Method for the Bearing of Reciprocating Compressor based on LMD Multiscale Entropy and SVM
Published 2015-01-01“…Aiming at the non-stationary and nonlinearity characteristics of reciprocating compressor vibration signal,a fault diagnosis method for bearing fault of reciprocating compressor based on LMD multiscale entropy and SVM is proposed.To improve the envelope approximation accuracy of local mean and envelope estimation,cubic Hermite interpolation method is used to construct envelope curves between extreme points according to the excellent characteristic of shape preservation.The vibration signals in each state are decomposed into a series of PF components with the improved LMD method,and the PF components which contain the main information of fault state are chosen according to the relative coefficient.By using the multiscale entropy,the quantitative description of the PF components is carried out,and the optimized scale factor is selected based on the maximum of average distances between different states,so the eigenvectors which have the best divisibility are extracted.The SVM is taken as pattern classifier,the type of bearing clearance fault is diagnosed,and the superiority of this method is verified by comparing the eigenvectors extracted by LMD and sample entropy and LMD and approximate entropy method.…”

Finite Element Simulation Analysis of Aqueduct by Auxiliary Pier Reinforcement
Published 2020-01-01“…With an aqueduct as the engineering background,this paper establishes a finite element model of spatial entity by auxiliary pier reinforcement,analyzes the force of each construction stage before and after the aqueduct reinforcement with consideration to the material nonlinearity of concrete,and compares and analyzes the influence of different jacking forces on the reinforcement effect.Through calculation and analysis,the following conclusions can be drawn:①The structural stress, deformation and crack width of the aqueduct can be significantly reduced by auxiliary pier reinforcement method.②The reinforcement effect can be enhanced with a suitable jacking force during aqueduct reinforcement.③When the jacking force is gradually increased from zero,the vertical displacement of the aqueduct after reinforcement is reduced first and then increased,the maximum principal tensile stress of the aqueduct after jacking and reinforcement also shows a trend of decreasing first and then increasing.④The jacking force should not be too large.Otherwise,the upper edge of the aqueduct will easily crack at the mid-span position and its adjacent position.Comparative calculation and analysis of the jacking force is required before reinforcement construction.…”
