| Abstract: | Determination of minimum sample size and selection of extrapolation methods play important roles in compiling load spectra,so accurately mastering the two key technologies has significance for compiling load spectra.By contrasting various methods of determining the minimum sample size,different application scopes of these methods are identified,and advantages and disadvantages of each determination method is analysed.Meanwhile,parameters evaluation method and rainflow matrix extrapolation method are offered... |
