Random Vibration Data Analysis Based on MATLAB and Tabular Parameter Input
MATLAB is often used to analyze random vibration data in time domain and frequency domain,draw the time domain data curve and the power spectral density(PSD)curve in the graph window,display the description parameters about the data such as measurement case,channel code,channel name,data description.It takes a lot of work and is inefficient to manually input the data description parameters for multichannel vibration data.A method is presented to improve the efficient of random vibration data analysis,which saves the description parameters as a table file using the efficient editing and inputting function of table software,automatically reads the table file using the appropriative function in MATLAB program,and then displays the description parameters in the graph windows.
