Vibration Analysis of the Damaged Bearing Unit of the Port Crane Lifting Mechanism

The methods of periodically non-stationary random processes were used to analyze the vibrations of the damaged bearing unit of the lifting mechanism. To identify and analyze the periodical nonstationarity of the first and second orders the least squares method was used. Based on the calculated param...

Description
Summary:The methods of periodically non-stationary random processes were used to analyze the vibrations of the damaged bearing unit of the lifting mechanism. To identify and analyze the periodical nonstationarity of the first and second orders the least squares method was used. Based on the calculated parameters, which describe the structure of periodical nonstationarity, a conclusion about the type of defect and its development was drawn.
