Before this evaluation a previous work in this field has been validated by an MATLAB program. Then, by considering five different types of void positions (five different cases of supporting), which commonly happen in sleeper and ballast interaction, the results for these situations are discussed. In order to clearly understand and interpret the behavior of the flexural modes, the shapes of them, for a simple theoretical case, are presented. To find out the frequencies of the sleeper and to find out the variation of 1st mode and 2nd mode rigid-body frequencies different MATLAB programs have been developed and through these programs frequencies for different void configurations with different void length have been calculated. The graphs generated show the variation of the frequencies for different void length. Copyright@ International Science Community Association
