| Abstract: | This paper discusses the statistics (mean value and standard deviation) of the structural natural frequencies. Using this method engineers are able to estimate the errors of structural natural frequencies caused by random structural parameters in finite element analysis. This method, because of its simplicity and effectiveness,can be applied to large-scale engineering structures such as high buildings, aeroplanes and rockets. |
