| Abstract: | It becomes increasingly important to improve the dynamic behaviour of the machine structure by way of optimization after the modal analysis of the machine has been made. Three methods for such analysis were developed and recommended in the paper. They were verified and assessed both in theory and in calculation technique, Practical examples of their application are given with satisfactory results. |
